"Error in matrix(0, 48000, 48000) : too many elements specified" but I thought it was a machine limitation (and I was asking for access to a better machine in my labs...). Thanks for clarifying it. Well, when Sarah gave me the answer for my problem, I got a new one :) Thank you, Sarah and Peter. So, is there any other way to "trick R" and allocate such large matrices?
Either 1) Use the development version of R which has large-vector support (matrices are vectors under the hood) or 2) A large matrix is usually sparse in structure: use one of the many sparse representation packages (e.g., Matrix) available. MW
