Temporarily changing the library path You can modify R's notion of your library path on a one-time basis by specifying the lib= argument to install.packages. Suppose there is a directory called MyRlibs in your home directory. The command: install.packages('caTools',lib='~/MyRlibs') will install the specified package in your local directory. To access it, the lib.loc= argument of library must be used: library('caTools',lib='~/MyRlibs') 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 The.libPaths() function accepts a character vector naming the libraries which are to be used as a search path. Note that it does not automatically retain directories which are already on the search path. Since the.libPaths() function returns the current search path when called with no arguments, a call like.libPaths(c('~/MyRlibs'.libPaths())) will put your local directory at the beginning of the search path.

This means that install. Download Iclone 5 Props Free. packages() will automatically put packages there, and the library() function will find libraries in your local directory without additional arguments. Permanently changing the library path 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. Korea S Nuclear Program 2007 Range.

This variable should be set to a colon-separated string of directories to search. Since it's always set inside of an R session, the easiest way to get a starting point for it is to use Ceramah Lucu Dari Jawa Timur. Sys.getenv(): >Sys.getenv('R_LIBS') [1] '/usr/local/linux/lib/R/site-library:/usr/local/lib/R/site-library:/usr/lib/R/site-library:/usr/lib/R/library' You could then make a copy of this path, modify it, and set the R_LIBS environmental variable to that value in the shell or a startup script.
