Dear All,
I have large matrix (46000 x 11250). I would like to do the linear
regression for each row. I wrote a simple function that has lm() and
used apply(mat,1,func). The issue is that it takes ages to load the
file and also to finish the lm. I am using LINUX 64 bit with 32G
mem. Is there an elegant and fast way of completing this task?
Do bigmemory and biglm help?
