boxplot(data.frame(mat)) is how it's described in the help, but it
produces the problem that began my discussion (i.e. prepends an "X" to
the name for a dataframe column name).

However, boxplot(as.data.frame(mat)) as suggested by Brian works fine.
So I needed only three keystrokes to get round the problem.

Thank you all.
