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.
