[R] Box Plot With Groups being numbers

[stephen sefick]

I would like to Summarize values that are repeated measures at a
certain river mile with box plot i.e.

The data matrix looks like this
123  124  125                  #fiver mile
0.5   0.6   0.7
0.4   0.5   0.6
...    ...     ...                    #values

I would like to make a boxplot with the river mile naming the
different box plot.  How do you suppress the X123?
