[R] Matrix library, CHOLMOD error: problem too large

[Jose Quesada]

I have a pretty large sparse matrix of integers:
> dim(tasa)
[1] 91650 37651

I need to add one to it in order to take logs, but I'm getting the  
following error:

> tasa  = log(tasa + 1)
CHOLMOD error: problem too large
Error in asMethod(object) : Cholmod error `problem too large'

I have 2 Gb of RAM, and the current workspace is barely 300mb.
Is there any workaround to this? Anyone has any experience with this error?

Thanks,
-Jose
