Can't use package in Julia - jupyter-notebook

Here is my code. I type all code in jupyter notebook.
I can use package normally last week. During the week, I didn't do anything in Julia. I don't know what happened. How can I solve this problem?
Does it mean that as long as I have downloaded the
package before in jupyter notebook, I will never have to download it again?
Thanks in advance.

Yes, once you download a package, it is saved into a specific environment. So assuming you don't switch Julia versions or create / activate a new environment, you will always have the packages you previously installed accessible to you.
You can double check what is installed in your current env by doing Pkg.status().

URL '/help/library/<package>/r/html/00Index.html' not found when using `devtools::load_all()`

I am using devtools::load_all as a workflow to iteratively make a package. However, I cannot seem to be able to view the package documentation using ? or help(package=package_name) until I install the package. The error I get is:
No documentation for ‘function’ in specified packages and libraries
and
URL '/help/library//r/html/00Index.html'
any suggestions on how to resolve this?
Thanks!
I guess the help(package=package_name) do nothing than open (in case of Windows) this file for you:
C:\Users\YourName\Documents\R\win-library\4.1\package_name\html\00Index.html
devtools::load_all make your latest functions available to you for testing without installing the package (i.e. the html file was not updated, and masked because it was belonged to the old version of your own package). To view your latest documentation (i.e. make a new version html), you can devtools::document() and check your package working directory \man\Functions_name.rd, OR, devtools::install() and help(package=package_name)
Just restarting r session solved my problem.

Cannot configure rgee R package properly with ee_install()

I've searched for tutorials to help configure the package in my PC, and I've found this one: https://www.youtube.com/watch?v=_fDhRL_LBdQ
I executed every part of the code interactively with the tutorial, but when I run ee_install() (after installing miniconda with py_discover_config() and other packages previously, such as reticulate), but it keeps me returning an error saying that anaconda is mandatory for the package since I'm a windows user.
Here is the error I get:
Error in ee_install_set_pyenv_env(py_env = py_env, py_path = python_path, : Windows users must install miniconda/anaconda to use rgee. The use of a Python environment is mandatory.
I've just installed Anaconda (full version with navigator) and I set a new python environment called "py2r" and tried to use the function ee_install_set_pyenv(), passing the path to the environment created through Anaconda Navigator (which has a python.exe) as paremeter to py_path and the name "py2r" as paremeter for py_env arg. And yet, it didn't work.
What am I missing?
In case you want to take a look at the code, I can provide it, but I don't think it's necessary because is a simple test script that follows as I described.
Thanks for your attention and congratulations for the library, it will be very usefull for me at work!
I fixed the ee_install() problems bypassing them and doing every passage manually. It will require no more then 10 mins and you will probably fix the installation problems. You can find and follow the manual installation with this tutorial:

Rstudio and R in command window in anaconda have different enviroments

I have a confusion when using R inAanaconda. I created an environment called "rstudio_env" and installed Rstudio in this environment. So far so good.
When I use Rstudio, I just open it without activating the "rstudio_env" and I also installed a lot of packages here. After updating the R through Rstudio, my new home path in Rstudio changes to some local default path. For example, the original .libPaths() = "C:/Users/someuser/.conda/envs/rstudio/lib/R/library" and new .libPaths()= "C:/someuser/Document/R/R-4.0.2/library".
Now when I use Rstudio, I have the new path. When I use R in the "rstudio_env" in conda, I still have the old path. This really confuses me, because I want to have the same libraries for both approaches. Why the updating changes the path of RStudio rather than only updating the contents?
I am too lazy to activate the "rstudio_env" when using Rstudio. That might be the reason for the conflict. But for now, how can I make the libraries consistent? I know I can change .libPaths manually, but are there other ways, some clearer ways?
I just reinstalled everything and made everything clean

Including a dataset in a R package

This question may seem pretty naive and I bag your patience.
I have saved extension.RData and documented it in extension.R. Both of them are saved in /data folder of the R package I am developing.
As I close RStuidio and reload the package, however, I cannot call the data until I execute one of the functions, devtools::document() or devtool::load_all(). Does this suggest that my dataset is not in memory of the package? How could I not to execute devtools every time I start working on the package?
Thank you very much.
As I have understood, you just created files extension.RData, extension.R (with documentation) in your project directory. However, this is not enough for RStudio to be able to reach your data. You have to install the package by running devtools::install() or clicking 'Build & Reload' button on 'Build' tab of RStudio.
Edit: Putting extension.R into R folder solves the problem.

Error while installing VIM package in R-2.15.3 [duplicate]

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.
