Hello, I'm trying to create a large matrix and it's extends the limit boundaries. The matrix is 100,000x2874 and R is throwing me out, what shall i do? Thanks Erez
Hi more memory new comp new OS think about possibility to reformulate the problem with help of database and loading/processing data in chunks. Couple of similar questions were answered not long ago so check archives.

Ezra I don't know what the elements of your matrix are, but if there are a large proportion of 0s you can work with sparse matrices in the Matrix package.
