  16. You can play with installing packages for R -- Alternatively, packages can be downloaded and installed from within R. First set the option CRAN to your nearest CRAN mirror using choooseCRANmirror(). Then download and install packages pkg1 and pkg2 by > install.packages(c("pkg1", "pkg2")) Unless the library is specified (argument lib) the first library in the library search path is used. If you want to fetch a package and all those it depends on that are not already installed, use e.g. > install.packages("Rcmdr", dependencies = TRUE)
