Hello,

I have a very large matrix which even exceeds the matrix dimension limits of R. How can I handle such large matrices and perform some basic operations on it?

Thanks

use big memory package?

bigmemory: Manage massive matrices with shared memory and memory-mapped files

Create, store, access, and manipulate massive matrices. Matrices are allocated to shared memory and may use memory-mapped files. Packages biganalytics, bigtabulate, synchronicity, and bigalgebra provide advanced functionality.
