I have Anaconda and I am learning to use it. I also installed R with it. It creates a separate enviroment " rstudio" with the default packages, but a lot of them appear with r-<name of the original package>, for example readxl is shown in the Anaconda enviroment as r-readxl. When I try to run in Rstudio, regardless of whether I type the original name of the package or the full "r-readxl" it does not find it. It says: there is no package called ‘r-readxl’.
Is there a way to tell Rsutdio that the packages in the Anaconda file are the ones of reference? How can I fix this?

I have installed R at following location C:\E_Drive\ProgramFiles\R-3.4.3, so I think R environment installed at C:\E_Drive\ProgramFiles\R-3.4.3 will be used when I run the R console, right? Please correct me if I am wrong.
Now, I install a package using the R console.
Now, I download and install RStudio and from the R console of RStudio if I check whether that package is available or not then I see that it is available. I am wondering, how RStudio's R console reported that package is available, I didn't expect that since C:\E_Drive\ProgramFiles\R-3.4.3 is not on my PATH and in no way is linked RStudio with C:\E_Drive\ProgramFiles\R-3.4.3, so I thought RStudio would be referring its own R environment.
Can you please help me understand how my RStudio is referencing the C:\E_Drive\ProgramFiles\R-3.4.3 R environment.
R normally installs packages in the same directory tree as its own binary, but it can also install them elsewhere. On Windows, this generally happens because regular users often don't have write permission in the Program Files directory. The standard Windows installer also records R's location in the registry, so that it doesn't need to be on the PATH to be found by RStudio.
You can find out where Windows or RStudio found R by running R.home() within R. You can find out where R is finding packages in a particular session by running .libPaths().
I just downloaded anaconda and downloaded their basic R package.
I also got some packages from anaconda, using the anaconda terminal commands that they provide on their website.
My question is -- when I am starting a new R session in r studio, do I still need to install.packages()? Can I just load the package?
When I press libary(rJava) for example -- the R command line doesn't say anything back on whether it was successful, that's why I'm not sure. Thanks.
if you have installed the R packages via the R command line then you can just directly load them. I would recommend that you use the command line rather than R studio.
I am trying to embed RInside to my application on win7 64-bit system but when I initialize an RInside:
Rin = new RInside(argc, argv);
the following message appears:
Error in loadNamespace(name) : there is no package called 'Rcpp'
This error only occurs with Windows.
I think you get that issue when your .libPaths() differ--in other words run the .libPaths() function to see the paths stored by R for its use. Then check where RInside is installed, and make sure Rcpp is installed there too. It is a setup issue.
In other words, it should work if you have Rcpp and RInside installed where the basic R libraries are. Otherwise you have to tell the (embedded) R session about the other location (and before it starts).
There are more Windows users on the list, so you could try asking on rcpp-devel.
First get your default library locations by command ".Library" in R.
Get Rcpp package from https://cran.r-project.org/web/packages/Rcpp/index.html.
Unzip and copy folder "Rcpp" to your default library locations obtained from step1.
Now you are ready to install packages which have dependencies on Rcpp.
Dirk is right in this case, BUT if the .libPaths() does not work, then please also check if you have the latest packages.
I am posting this as an ancillary answer backup which I ran into with the shiny package backend switch of their code needing Rcpp!
In this case of getting the "no package" error message, I fixed it by:
Selecting devtools package and then using this line below. (if you don't have devtools then get it with install.packages("devtools")
devtools::install_github("rstudio/shiny")
The development version of the package handled this better, and added the package as a dependency.
Mods - I realize this is an answer to an old question, but I might help others not wasting an hour like I just did.
You might find it easy if the answers are for both R studio users and non R studio users.
R Studio users
First get your default library locations by command ".Library" in R.
Get Rcpp package from https://cran.r-project.org/web/packages/Rcpp/index.html.
Unzip and copy folder "Rcpp" to your default library locations obtained from step 1, you will find another folder named library, paste the unzip folder in it.
Non R studio Users
First get your default library locations by command ".libPath" in R.
Get Rcpp package from https://cran.r-project.org/web/packages/Rcpp/index.html.
Unzip and copy folder "Rcpp" to your default library locations obtained from step 1, you will find another folder named library, paste the unzip folder in it.
I was also getting this error while trying to run the 'ggplot' function from the ggplot2 package. After trying the suggestions posted here and elsewhere (checking file paths, restarting R, clearing out my environment, etc.) and encountering several other cryptic error messages, it turned out that I needed to download the latest version of base R for Windows (v3.4.1) and update my version of R-Studio to the latest version also (v1.0.153).
After doing this my 'ggplot' function was working again and I was able to render my figure from R Studio without any further issues.
I was also getting this message when trying to use ggplot. I first updating both my R for Windows to 3.4.3. Then updating R studio to version 1.1.423; then, updating all of the packages and being sure to access the R version 3.4.3 from R studio, I still got the message. None of these things fixed the error. I was ready to give up until I noticed that I was calling library(ggplot) and had ggplot::ggplot in my code. THIS WAS THE PROBLEM. I changed it to library(ggplot2) and the instance to ggplot2::ggplot(...). THIS FIXEd the problems.
I was facing a similar issue, and I simply installed the said package. It's working perfectly for me.

I've installed a R package (PathRanker) that depends on packages (xml,Rgraphviz,Rcurl). I've noticed that the all the packages' folders inside the library shows some sort of a locked sign.
I tried to remove PathRanker using the R CMD REMOVE but it didnt works. I tried to reinstall the package (which I kindda mess around with the code) it also didnt works. So I think it got something to do with the dependency packages. Can someone help me? thanks...
You might have installed the packages as root (if you are using Linux), and trying to remove the package as normal user.
Start an R session as root (sudo R), and try to remove (see: ?remove.packages) the packages in this environment. Or from console:sudo R CMD REMOVE (package name)
If still not working, please write more about the error messages.
