[R] double matrix?

I have a 37 X 473971 character matrix that I am trying to convert into a 
numeric matrix. When I use the code:

 class(matrix) = "numeric"  

I end up with something called a "double matrix" whose dimensions are still 
37 X 473971

I have also tried 

new = apply(matrix,2, as.numeric) and got the same thing.

The analysis code I am ultimately attempting to run on this data requires 
that it be in a numerical matrix, and it is really not okay with a double 

Does anyone know how to fix this?
