I am not sure to understand what you want, but maybe
colnames() is what you want.
for example

> mat
     [,1] [,2] [,3]
[1,]    1    3    5
[2,]    2    4    6
> colnames(mat)<-c("col1","col2","col3")
> mat
     col1 col2 col3
[1,]    1    3    5
[2,]    2    4    6


was it what you were looking for ?
