[R] simple script help

[R. Michael Weylandt]

Put pdf() before your loop and dev.off() after -- as it stands now, on
each iteration you re-open the pdf and thereby wipe everything that
was previously on it.

For the axis, look at the axis() command if you want something
detailed or the xaxt, xlab arguments to boxplot if its relatively
simple.
