I'm working in RStudio and am attempting to install the dplyr package. I have installed various other packages without problem but have hit a problem with this.
It seems there are various parts to the install, some of these worked but the problem happens when I get 'the dependency BH'. This is the error:
>Installing package into ‘\\xxxxxxxx.local/Desktops/jagnew/My Documents/R/win-library/3.3’
(as ‘lib’ is unspecified)

I have changed the directory/libpath as it did not appear that the file was downloading to the correct folder. file142032c9327b is now in the correct path, but path specified in the error is only correct up to /boost, there is no function folder here..?
I'm not sure if this missing folder is the issue, as the error says 'Permission denied', but it seems odd.
I had the same issue. Tried doing the following and worked for me:
Run the RStudio as administrator
Under the Packages tab, click Install and change Install to Library option to C:/Program...../R/../library and select the desired package to install.
Hope it works.
I had the same problem. R gave me an error message whenever I tried to install a new, or update an existing package. I don't remember what the message said exactly, but it was saying "Cannot open file (...) access denied". I tried all the following. Not sure what exactly fixed the problem, but now I can update and/or install new packages:
Open R/RStudio as administrator;
Change the R library folder (where packages are installed) security settings, and grant full access to my computer user account. Link1, link2;
(I think this was what fixed the problem) Follow instructions on this link. It prompted me to install another package, "devtools". Then it worked.
Well, I think my problem was a special case, but it might benefit someone. I had the Windows Defender Ransomware Protection set to ON. That was blocking rsession.exe by default. Allowing rsession.exe solved the problem.
TL;DR
The "Documents" (or "My Documents") directory is a special location in Windows. I don't know if the system itself processes its permissions differently or if antiviruses target operations inside this directory more strictly, but many R users have issues installing packages in the personal library inside this folder (even if running R as administrator). Other answers haven't worked.
For me, what solved the problem was to put the personal library directly under X:\\Users\username\ instead of under Documents, which is the R default on Windows. To make it permanent, I set a user environment variable R_USER to %USERPROFILE%. Here is a nice guide of how to set environment variables in Windows.
Note: after this change, you may need to move your .Rprofile, .Renviron, etc. files from Documents to the user profile directory.
Details
The default location for R's user "home" directory on Windows is X:\\Users\username\Documents. This is because there is no concept of HOME in Windows, just of a "personal" directory (Documents): https://cran.r-project.org/bin/windows/base/rw-FAQ.html#What-are-HOME-and-working-directories_003f
Therefore, by default, the personal library location is under X:\\Users\username\Documents\R\win-library\X.Y\. You can get the exact location on your machine with this command in the R console:
Sys.getenv('R_LIBS_USER')
I was getting this same cannot open file error when trying to install or update packages, even when running as administrator. I suspected of directory permissions, checked it within the directories' "properties" without luck. Removed the whole R\win-library tree and recreated it and nothing... Finally, I tried to move the personal library location to my users' directory:
.libPaths('X://Users/username/R/win-library/X.Y/')
And it worked!
Warning in install.packages :
cannot create file '/usr/local/Cellar/r/3.6.2/lib/R/doc/html/packages.html', reason 'Permission denied'
Warning in install.packages :
cannot update HTML package index
I had the same permission issue when trying to download a pkg--ISLR. Fixed it after following the above answers.
In case, some are new to R studio like me. These were my steps to install a pkg.
Click Terminal next to Console in R studio
Type sudo r, to run r as an administrator
install.packages("ISLR") to install your package

Voilà! Package installed.
I had faced also this issue. The one and only solution that helped me was to turn off my firewall. Then I was able to download all packages.
The problem solved for me after running R in admin mode and disabling Antivirus.
Translating #Shubham Yadav's answer to code mode would be something like this: install.packages("your_package", lib = "C:/Program Files/R/R-4.0.3/library")
It's working for me (running RStudio as admin, course).
This procedure worked for me.
Removed existing package with remove.packages()
ran RStudio as an admin
Installed by specifying the libpath: devtools::install_github('https://github.com/Rdatatable/data.table/tree/frollmax', lib=.libPaths()[2])
For me what worked was manually deleting within the library directory the folder that I had problem with updating. And then install.package() again.
I had faced the same issue.
I tried below steps to resolve this issue:
Launch RGui application.
Go to Packages section and select Install Packages.
Select the Package that you want to install from the Packages pop up window.
And click OK, that's it package will get successfully installed.
After following above steps, you can run use your package from RStudio.
I ran into this issue today where rlang couldn't install the newest version and so tidyverse wouldn't work. I tried running as admin, changing install location, running as admin, permitting rstudio through Windows Defender Randsomware Protection, and installing DevTools. The only thing that worked was to uninstall RStudio, reboot, reinstall.

I'm trying to update packages on RGui (64-bit) using update.packages but I'm getting the following message:
Warning in install.packages(update[instlib == l, "Package"], l, contriburl = contriburl, :
'lib = "C:/PROGRA~1/R/R-212~1.1/library"' is not writable
Error in install.packages(update[instlib == l, "Package"], l, contriburl = contriburl, :
unable to install packages
I've looked at the library folder in Explorer and it has read only set, so I removed it. However, it reappears when I check the properties again immediately after doing this. Installing new packages is unaffected since they have a separate folder in my user profile.
Is there a trick to getting this to work?
It happens the same to me, and after coding hours and hours in "R" of Gui Project, i got bored because it is much easier to read a code when the interface uses colours for a certain type of words (commands). Well, i decided to install RStudio, but soon i was faced with package installation problems. It seems that happens in Windows 7. The way that I used to solve this problem with RSutido was:
C:\Program Files\R - and this is the folder that contains "R" and not RStudio folder!
Right click for properties.
Security.
In "Group or user names" select your name
click "Edit"
select "Full control"
Apply and click OK
After this steps you should be ok to install all the packages :-)
Usually you need administrator rights to change things in program files. Try running RGui as administrator.
try
install.packages('package_name', lib='folder')
you can specify a folder for installation of the libraries, for which you have writing permission.
Hope this helps
Uninstalling from C:\Program Files and re-installing to C:\R worked for me
[See mdsumner's comment and Windows FAQ found here]
"...Users of Vista/Windows 7/8/Server 2008/2012 installing for a single user using an account with administrator rights1 should consider installing into a non-system area (such as C:\R)"
I had this exact problem and just changed it for myself. That is I navigated to C:/PROGRAM/R and then right clicked on the R to bring up properties. Went to the Security tab clicked on the Group/User that you want to add permissions for. That for me was USER then clicked EDIT and then selected the boxes that were unchecked to Allow control over. I had to do this specifically for each user (of course I was running the entire time as administrator). Clicked Apply/OK and all is well. I can now update/install/ new libraries and what have you for this computer without having to run R as the admin.
Without more information, my first guess is that you have insufficient permissions to write to the R site library folder. Usually, R would prompt for creation of a user lib folder to install to, but this can be unreliable under Windows Vista/Windows 7.
Try:
dir.create(Sys.getenv("R_LIBS_USER"), recursive = TRUE)
In the R console. Libraries should now install to /Users/"you"/R/win-library/x.y, for which you have the appropriate permissions.
I have BitDefender 2018 and had to disable "safe files" and "firewall".
I had a similar error recently. Running RStudio as an administrator didn't work. And changing the permissions on C:/Programs/R is a bit clumsy, as you'd have to repeat it for every user.
The solution for me was changing the library path for R as follows
In the R console, type .libPaths(). You'll see something like this,
"Path/to/user/R/win-library/x.x" "C:/Programs/R/R-x.x.x"
The two paths exist because you have defined a user-specific lib path during installation. Replace x.x.x with your R version.
Now set the lib path to the Programs directory
.libPaths = "C:/Programs/R/R-x.x.x"
Now you can install.packages() or update.packages()!
Try choosing a cranmirror location closer to you with this command first
chooseCRANmirror()
And then try installing the package. This command worked for me when I was getting warnings on installing "devtools".
I also had this kind of problem in Windows 10, Then I disable "Safe Files" in Bitdefender 2018. It works for me
Sometimes there may also be a possibility that your Antivirus is blocking the application. Unblock the application if anti virus has blocked it.

I am using R 2.13.0 with windows 7, after giving my user full privileges to the R folder (as described here).
This allows me to install new packages just fine.
However, when using update.packages(), to update existing packages, I keep getting the following error (for example, when updating the MASS package):
package 'MASS' successfully unpacked and MD5 sums checked
Warning: unable to move temporary installation
'C:\Program
Files\R\R-2.13.0\library\file6cae3bcf\MASS'
to 'C:\Program
Files\R\R-2.13.0\library\MASS'
Any suggestions on how to fix this?
p.s: Running R as an administrator or shifting the library location out of Program Files is not a solution (it's a hack - but I am looking for a solution)
I found that the problem indeed is the antivirus "real time file system protection". I do the following to fix the problem:
trace(utils:::unpackPkgZip, edit=TRUE)
I edit line 140 (line 142 in R 3.4.4):
Sys.sleep(0.5)
to:
Sys.sleep(2)
I seems like the antivirus stalls the creation of the package tmp dir. After changing it to 2 seconds the error is gone.
EDIT: to do this programmatically execute
trace(utils:::unpackPkgZip, quote(Sys.sleep(2)), at = which(grepl("Sys.sleep", body(utils:::unpackPkgZip), fixed = TRUE)))
(credits #DavidArenburg)
Just to update everyone, I (think that I) found out the source of the problem: antivirus.
The "real time file system protection" was blocking R from copying the files between folders once they were downloaded.
Upon adding the R directory to the exception list (coupled with adding user permission and installing R on D:\R), and the problem went away. With all of this work, I might as well switch to Linux (I should, really...)
(I updated my post with the above information: http://www.r-statistics.com/2011/04/how-to-upgrade-r-on-windows-7/)
I hope it will help someone in the future,

If you cannot turn off your antivirus, due to corporate policy for example, here is a workaround that I found. Debugging the unzip package function and then stepping through it gives the antivirus enough time to do its job without interfering. Use this command:
debug(utils:::unpackPkgZip)
install.packages("packageName")
and then step through the code (by pressing enter many times) when R starts debugging during the installation.
I found this solution here.
If you can just download the binary straight from CRAN. On windows when downloaded it will be a zip file. Now manually unzip this into the ..library/ folder of your R (.libPaths()). It worked for me on some packages.
I had this problem installing both swirl and dplyr. I am working on Windows 64-bit.
Warning: unable to move temporary installation
What I did is I accessed my temporary files on the C: drive, and opened my file extractor program and I extracted the files from the temp file in the C: drive to my R program files in the C: drive, by manually copying them. THIS WORKED FOR BOTH dpylr and swirl. Stoked!

Can you not use the lib.loc parameter to only update packages in your personal library (in user)?
There should be no way to enable a normal, non-augmented user to change files in the program files folder, so the only thing you can do (if you don't want to augment the user) is to have R not updating packages there.
A workaround is to avoid installing R in the program files folder (which may be more or less of a hack than just shifting the library location out of it, depending on your point of view).
Finally, if lib.loc doesn't cut it, you can look at the source code for update.packages and create your own customized version that will always avoid the common library location in program files.
I just met the same question, and the solution I found out was that you should install packages using the original R software (plus, you should choose the right mirror site, some of them are blocked). At first I used Rstudio to install packages and I got the same problem as you met. Hope this is helpful.
I have run into this error several times. In my own case, it is because our admins want us to use remote virtual disks (on Windows 7) for our files and everything is locked up tight as a drum. The only way I can use R packages is in a lib directory on that remote virtual disk. This wouldn't be a problem except that the network isn't always smooth and fast. Thus, when I need a package, especially one with several other packages in tow (e.g., MBESS), I either have to go through the get.packages() process multiple times until it finally finishes or make it IT's headache to do quick like the bunny for me. I can't always wait for IT.
I just went to the library folder (Windows XP) and deleted all fileXXXX folders. Reran the install an it is worked.
I had the same problem. Since the issue seems to be the antivirus blocking the transf of a downloaded file, I tried a different download method in the install.packages and it worked.
For example:
install.packages("stringr", method = "curl")
You must go into the properties of the R folder and change the security parameters. You can enable the option to write and modify for all users.
The error : "unable to move temporary installation" is basically arising due to any of the antivirus running on your system.
Try unzipping the downloaded file from the Temp folder into the default library path (you can get it by running .libPaths() in R session).
I'm using a MRAN and I was having so many versioning issues. Trying to work with tidyverse and ggplot2 and by upgrading to the latest version from Microsoft it solved all of my R-Studio versioning issues.
