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. Hue University, VietNam.
