[R] easy way to cap a data frame to a max value

[Grey Moran]

Hello,

I have some rather large matrices.  Is there a way (without having to
loop) to cap all the values of a data frame to a given ceiling?
E.g.
junk <- cbind(c(1,2,3,4,5),c(2,4,6,8,10))
> junk
     [,1] [,2]
[1,]    1    2
[2,]    2    4
[3,]    3    6
[4,]    4    8
[5,]    5   10

>" replace anything over the value of 5 with 5..."

Thank you all,

Grey
