This R Companion to Introduction to Statistical Investigations (Preliminary Edition) by Nathan Tintle et al provides
- a companion text demonstrating how to use R to perform the analyses in that book
- an R package (
ISIwithR)
The campanion text is available as a PDF [to view] or [to download]
- The authors are Randall Pruim and Lana Park.
The ISIwithR package can be installed from github using
devtools::install_github("rpruim/ISIwithR")This package contains
- all of the data sets used in the book, and
- the
isa_snippet()function which can be used to run any of 463 code chunks from the campanion.
For example:
require(ISIwithR)
require(mosaic)isi_snippet("Exploration6.3.8")
#>
#>
#> isa_snippet(Exploration6.3.8)
#> ------ ~~~~~~~~~~~~~~~~
#>
#> > Friends.null <- do(1000) * diffmean(friends ~ shuffle(sex), data = CloseFriends)
#>
#> > head(Friends.null, 3)
#> diffmean
#> 1 0.15596895
#> 2 0.04284731
#> 3 -0.20546848
#>
#> > histogram(~ diffmean, data = Friends.null, width = 0.05,
#> + group = cut(diffmean, c(-0.4, -0.228, 0.228, 0.4)),
#> + fcol = c("steelblue", "navy", "steelblue"))
