[R] PCA and automatic determination of the number of components
Hi all, I have relatively small dataset on which I would like to perform a PCA. I am interested about a package that would also combine a method for determining the number of components (I know there are plenty of approaches to this problem). Any suggestions about a package/function? thanks, Nick -- View this message in context: http://www.nabble.com/PCA-and-automatic-determination-of-the-number-of-components-tp23129941p23129941.html Sent from the R help mailing list archive at Nabble.com.

You can also use parallel analysis using the scree.plot function of the "psy" package.
