Hi All, Some time back I had asked the question about PCA results not matching between R and MLIB. I was suggested to use svd.v instead of PCA to match the uncentered PCA . But the results of mlib and R for svd do not match .(I can understand the numbers not matching exactly) but the distribution of data when plotted does not match. Is there something I can do to fix. I mostly have tallSkinnt matrix data with 600000+ rows and upto 100+ columns . Any help is appreciated . Thanks _R
