Hello,

I'm having a problem installing CEM package in R.   Once I run "install.packages("cem",repos="http://r.iq.harvard.edu", type="source")", I get a following error: "ERROR: dependencies 'randomForest', 'combinat' are not available for package 'cem'
* removing 'C:/Program Files/R/R-2.15.2/library/cem'".   I tried to run "library(CEM) next, but of course R can't find the package called CEM.    Can someone please help me with this?

 

Thank you
