CHAID package installed from source in R

Question

I have installed CHAID package in R for Windows in the following way:

1. installed the Rtools31.exe
2. installed the package from source: install.packages("CHAID", repos = "http://R-Forge.R-project.org", type = "source")

When I try to see the help documentation for CHAID I run : ?CHAID() the following error message appears:

"Error in .helpForCall(topicExpr, parent.frame()) : 
  no methods for ‘chaid’ and no documentation for it as a function"

This means the CHAID package hasn't been installed? when I run the installed.packages() the following line appears:

        Package                                        LibPath   Version   Priority     
CHAID   "CHAID"  "C:/Users/JJJJJJ/Documents/R/win-library/3.1"   "0.1-1"         NA        

Answer 1

From what you write it appears that you have installed the CHAID package correctly. To use it within R, you need to load the package via

library("CHAID")

and the main fitting function is chaid() . To view its manual page you can use either one of

?chaid
help("chaid", package = "CHAID")

and some examples can be carried out by

example("chaid", package = "CHAID")
