[R] short way

i want to replace certain values of a matrix.
i know how to replace them when the values are in a vector.
i tried the same way for a matrix and got this answer:

la[la==0]<-1
Error in [<-.data.frame(*tmp*, la == 0, value = 1) : 
        matrix subscripts not allowed in replacement

i found a way to do this with "for()",
but i think this is the worst way to do it.

So is there a better way?
