Nothing
This package contains data sets and some utility functions to support Foundations and Applications of Statistics: An Introduction Using R by Randall Pruim.
The package can be installed from CRAN via
install.packages("fastR")
or from github
devtools::install_github("rpruim/fastR")
In addtion to data sets, fastR
contains a snippet()
function that
loads and executes code found in the text. Here is an example:
require(fastR)
require(multcomp)
snippet("bugs")

#> Tukey multiple comparisons of means
#> 95% family-wise confidence level

#> Fit: aov(formula = sqrt(NumTrap) ~ Color, data = bugs)
