Efficient Package for Huge datasets in R
Dear Sir/Madam,
I have a large data set of 10,17,289 observations of 10,830 variables. I
need to use PCA to reduce the dimension of dataset. I have already tried
irlba, prcomp and nsprcomp packages in R but couldn't do for huge data
sets.

able to get only few PCs for 5000 rows only
so can you
