[R] Principal component analysis with EQUAMAX rotation

Hello, I need to do a principal component analysis with EQUAMAX-rotation. Unfortunately the function principal() I use normally for PCA does not offer this rotation specification. I could find out that this might be possible somehow with the package GPArotation but until now I could not figure out

[R] RGL and Windows 7

Hi! For saving 3d plots I make use of the "rgl.snapshot" command provided within the rgl-Package. So far there was no problem using Windows XP, but under Windows 7 the result is a black image, however in the png-format (see attachment http://r.789695.n4.nabble.com/file/n2844487/Koll_perf.png ).

Re: [R] RGL and Windows 7
