If you install R in any "normal way", it comes with 29 R
packages.

Inside, R, you get their names via

> rownames(installed.packages(.Library,
priority=c("base","recommended")))
 [1] "base"       "boot"       "class"
"cluster"    "codetools"
 [6] "compiler"   "datasets"   "foreign"
"graphics"   "grDevices"
[11] "grid"       "KernSmooth" "lattice"
"MASS"       "Matrix"
[16] "methods"    "mgcv"       "nlme"
"nnet"       "parallel"
[21] "rpart"      "spatial"    "splines"
"stats"      "stats4"
[26] "survival"   "tcltk"      "tools"
"utils"

A subset of  14  of these, the "base" ones, are bundled with R,
and entirely part of the source code of R, and hence cannot be
installed separately :

> rownames(installed.packages(.Library, priority="base"))
 [1] "base"      "compiler"  "datasets"
"graphics"  "grDevices" "grid"
 [7] "methods"   "parallel"  "splines"
"stats"     "stats4"    "tcltk"
[13] "tools"     "utils"

Package 'stats' is among these and even is among those packages
that are loaded and *attached* (to your "search path") by default,
when you start R.
