using apply with sparse matrix from package Matrix
Hi:
I was trying to use apply on a sparse matrix from package Matrix,
and I get the error:
Error in asMethod(object) :
Cholmod error 'problem too large' at file ../Core/cholmod_dense.c, line 106
Is there a way to apply a function to all the rows without bumping
into this problem?
Here is a simplified example:
> dim(sm)
[1] 72913 43052
> class(sm)
[1] "dgCMatrix"
attr(,"package")
[1] "Matrix"
> str(sm)
Formal class 'dgCMatrix'...
