Subject: How to create a high-dimensional matrix
In-Reply-To: <CAAmySGNJ2XnvEoQU4-GP7UOWLBMOKYF=ejHnE1FQS4g+9y-DRQ@mail.gmail.com>
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 first.
