[R] Force labelling of x-axis

[Bill Kranec]

Hi,

I'm trying to do a box-whisker plot of two columns of a data frame, a
list of category names in one column vs. some numerical values in the
other.  The plot itself works fine, but only a few points of the x-axis
( the category names ) are labelled.  I think that this is because the
category names are too long.

Is there any way to force R to label each x-axis value, preferably at a
45-degree slant so that each one can be seen?  I feel like this should be
pretty easy to do, but I can't find anything obvious from the R-manual.

Thanks for any help,

Bill
