Like this, for instance:

> h<-c(3, 3, 3, 3, 2, 2, 2)
> n<-5
> matrix(h, nrow=n, ncol=length(h), byrow=TRUE)
     [,1] [,2] [,3] [,4] [,5] [,6] [,7]
[1,]    3    3    3    3    2    2    2
[2,]    3    3    3    3    2    2    2
[3,]    3    3    3    3    2    2    2
[4,]    3    3    3    3    2    2    2
[5,]    3    3    3    3    2    2    2
