Dear Ms/Mr,
In a package, I want to use PCA function. The structure I used follow this
page: http://www.statmethods.net/advstats/factor.html.
       fit<-principle(mydata, nfactors=9, rotation=TRUE)
   or:
       result<-PCA(mydata)

But I don't known why R language in my computer noticed: "not found
principle", "not found PCA".
I download and installed R-2.6.2-win32.exe.
Thanks alot for answering me.
