Not sure if these are relevant as they have been on my "must look at" list for some time and I've not managed to get around to it ...

Hello all,
I was wondering if R has some routine that can handle PCA with a lot of zeros. I have fourteen variables - these variables represent angles...so there are some negative and some positive angles. Histograms appear sparse
- in the sense that there are gaps. Any ideas or papers would be greatly appreciated.
