Re: [R] max size of a matrix

Are you aware that that matrix will have 147456^2 elements each of size 8 bytes ("double") resulting in R trying to allocate (147456^2)*8/1024^3 = 162 GB of RAM? If you are aware of this and still trying to allocate a large matrix, it is unfortunately too large due to "technical" limitations in R.

[R] max size of a matrix

Hi R users, I am trying to create a matrix, but R has problem with the size of dim, wondering if there is anything that I can do? > a <- diag(147456) Error in array(0, c(n, p)) : 'dim' specifies too large an array Thanks for your help Rostam [[alternative HTML version deleted]]
