![]() The content of these environment variables is added to the package search path in the order listed. There are three environment variables which control the content of the path vector: libPaths(”) (with an empty string) will remove all other entries but the library sub-directory of the distribution. The last element of the path is R’s distribution library path. Thus, it is important to understand how the vector of paths is build. ![]() If the package is found, it is loaded and the search finishes. When the user requests a package to be loaded (via require or via library), R searches for the package in each path of the list, starting with the first. The result is a vector of strings, each representing a path containing packages. libPaths() function (invoked without arguments). R’s package search path is reported by the. For these packages to be found by R, the rsite folder (its absolute path, for instance c:/users/ivannp/rsite) needs to be added to R’s search path. Above quantmod, TTR, xts and zoo are all folders each containing the corresponding package. ![]() Despite the documentation, it did require additional reading and experimentation.īefore getting into package search paths, let’s first figure out how does an R package look in the file system:Īn R package is a folder somewhere in the file system. This came down to understanding where does R store and search for packages. I'm not sure if that's the way it was before the network drive usurpation.Recently, while working on the Azure Data Lake R extension, I had to figure out a good way to create a zip file containing a package together with all its dependencies. Right now both versions have the same Sys.getenv("HOME"). Is there a way I can set it up so it checks which version of R is being launched and then automatically switches the library path to the appropriate directory? For example, if I launch R 4.0.4 it automatically defaults the library path to "C:/newplace/R/win-library/4.0" and if I launch R 3.3.30 it does the same but for "C:/newplace/R/win-library/3.3"? Renviron file with the line above, it changed the library paths for both the old and new version to the same place: "C:/newplace/R/win-library/3.3". Before this, the newer version (4.0.4) automatically used a library path of "C:/Users/myname/Documents/R/win-library/4.0" whereas the older version (3.3.0) automatically used a library path of "C:/Users/myname/Documents/R/win-library/3.3". However, I have multiple versions of R installed on my PC. R_LIBS_USER = "C:/newplace/R/win-library/3.3" # and then I added the following line, saved it and restarted R: The solution that made the most sense to me was to modify the. As I do not have administrative privileges to force delete them, I figured the best workaround was to simply change where R installs packages to an offline folder I can control. This has started creating all sorts of issues where I cannot install, update, or remove some R packages with dependencies because some subfolders get corrupted and I cannot even delete them. I'm having an issue where my work organization setup a network drive that has disrupted my R experience, usurping the Documents folder of the C: and making it one and the same with the network version of it, which therefore moved R's home environment ( Sys.getenv("HOME)") and the package installation folder (.
