can't install "CHAID" on Mac OS X 10.9.5 - r

Question

I have encountered a problem of installing CHAID package on my Mac. I am not sure if it is a problem of my Mac OS version or some other problems. Could anyone help?
Thank you so much!!

Answer 1

You first need to install the 'partykit' package (and all of its dependincies) and then issue this command:
install.packages("CHAID", repos="http://R-Forge.R-project.org", type="source")
This is the transcript on a Yosemite machine but I think this should also succeed on Mavericks. (You can notice that there is no invocation of compiled code, so I do not need to warn you that XCode might be needed.)
