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. i.e pc <- prcomp_irlba(sparseYY[1:5000,], n=50, retx = TRUE, center = TRUE, scale. = FALSE) able to get only few PCs for 5000 rows only so can you please help me what package can i use to do PCA in R for large dataset? Thanks and Regards [[alternative HTML version deleted]]
