Hello,

I have a dataset with 20,000 variables.and I would like to compute a pearson
correlation matrix which will be 20000*20000. The cor() function doesnt work
in this case due to memory problem. If you have any ideas regarding a
feasible way to compute correlations on such a huge dataset, please help me
out.

Please feel free to share your memory handling techniques in R.

Thanks,
Suman
