The environmental variable R_LIBS is set by the script that invokes R, and can be overridden (in a shell startup file, for example) to customize your library path. This means that install.packages() will automatically put packages there, and the library() function will find libraries in your local directory without additional arguments. Will put your local directory at the beginning of the search path. libPaths() function returns the current search path when called with no arguments, a call like. Note that it does not automatically retain directories which are already on the search path.

libPaths() function accepts a character vector naming the libraries which are to be used as a search path. One problem with this scheme is that if a local library invokes the library() function, it won't know to also search the local library Changing the library path for a session To access it, the lib.loc= argument of library must be used: library('caTools',lib='~/MyRlibs') Will install the specified package in your local directory. The command: install.packages('caTools',lib='~/MyRlibs') Suppose there is a directory called MyRlibs in your home directory. You can modify R's notion of your library path on a one-time basis by specifying the lib= argument to install.packages. If you need more control over the library path, R provides a number of methods for controlling the library path to accommodate just about any user's need. libPaths() to check that the user-level directory is the default location (it should be the first result printed, as seen below) where R will install packages. The simplest solution is to create the directory: mkdir -p ~/R/x86_64-pc-linux-gnu/4.2

Mkdir: cannot create directory '/server/linux/lib/R/site-library/00LOCK': Permission denied ERROR: failed to lock directory '/server/linux/lib/R/site-library' for modifying However, if that directory does not exist, you may get an error message like this: So if you need a package quickly or on a one-time basis, or if the package is particularly specialized, you might install it locally.īy default, user-installed packages are installed in the `R` subdirectory in your home directory, in ~/R/x86_64-pc-linux-gnu-library/4.2. However, you can also install packages locally within your home directory.
