6 of one; half dozen of the other. Your matrix is still absolutely
massive: the development version of R does allow for lager matrices so
I think you can store a 429497 by 429497 in memory then, but it
Should it be .Machine$integer.max- 429497 ^2?
The matrix is not a sparse matrix, but a symmetric matrix.
It's a process of feature selection. I am choosing the most important
variables from 439497 variables. Now I am considering divide the whole
dataset into several part and process a small part
