Hello All,

On the subject of boxplots, I have multiple data sets of unequal sample
sizes and was wondering what would be the most efficient way to read in the
data and plot side-by-side boxplots, with options for controlling the
orientation of the plots (i.e. vertical or horizontal) and the spacing?   Your
assistance is greatly appreciated, but please try to be explicit as I am no
R expert.  Thanks

Janh
