![]() ![]() This is only an issue if you have more than one library, of course.Įnsure that the environment variable TMPDIR is either unset (and /tmp exists and can be written in and executed from) or is the absolute path to a valid temporary directory, not containing spaces.Īv <- available.packages( filters= list()) av = pkg, ] Note that you may need to specify implicitly or explicitly the library to which the package is to be installed. ![]() Binary packages are platform-specific and generally need no special tools to install, but see the documentation for your platform for details. Installing source packages which contain C/C++/Fortran code requires that compilers and related tools be installed. Packages may be distributed in source form or compiled binary form. This has a default value (to see it, use Sys.getenv("R_LIBS_USER") within an R session), but that is only used if the corresponding directory actually exists (which by default it will not).īoth R_LIBS_USER and R_LIBS_SITE can specify multiple library paths, separated by colons (semicolons on Windows). Users can have one or more libraries, normally specified by the environment variable R_LIBS_USER. See ?.libPaths for how to make use of the new value. 2 its binding is locked once the startup files have been read, so users cannot easily change it.
