R help - Mar 2007 - problem with putting Hmisc labeled matrix into a data.frame.

# I seem to be having a bit of a problem with Hmisc.
At least, I assume it is
# coming from there. When I try to put a labeled
matrix into a data.frame
# I get a very strange result. If you would run the
two examples I think
# you will see my problem.

# Example 1  no label
library(Hmisc)
mydata <- matrix(1:12, 3, 4)
myvec <- matrix( c("a","b","c"), 3)

mf <- data.frame(myvec, mydata) ; mf    # works fine

#  with label

ndata <- matrix(1:12, 3, 4)
label(ndata) <- "Great matrix"
nvec <- matrix( c("a","b","c"), 3)

nf <- data.frame(nvec, ndata) ; nf   #  Not so fine

>
> nf <- data.frame(nvec, ndata) ; nf   #
   nvec ndata.1 ndata.2 ndata.3 ndata.4
