To get the list of packages loaded by default, you can use the
getOption
command to
check the value of the defaultPackages
value:
> getOption("defaultPackages") [1] "datasets" "utils" "grDevices" "graphics" "stats" [6] "methods"
This command omits the base
package; the
base
package implements many key
features of the R language and is always loaded.
If you would like to see the list of currently loaded packages,
you can use the .packages
command
(note the parentheses around the outside):
> (.packages()) [1] "stats" "graphics" "grDevices" "utils" "datasets" "methods" [7] "base"
To show all packages available, you can use the all.available
option
with the packages
command:
> (.packages(all.available=TRUE)) [1] "KernSmooth" "MASS" "base" "bitops" "boot" [6] "class" "cluster" "codetools" "datasets" "foreign" [11] "grDevices" "graphics" "grid" "hexbin" "lattice" [16] "maps" "methods" "mgcv" "nlme" "nnet" [21] "rpart" "spatial" "splines" "stats" "stats4" [26] "survival" "tcltk" "tools" "utils"
You can also enter the library
()
command with no arguments and a new
window will pop up showing you the set of available
packages.
