R help - Mar 2013 - Creating a boxplot from a data summary

Hi,
I'm trying to create a boxplot from the summary of a large data set and
I'm
having trouble finding any way to do this.  I'm familiar with, but by no
means good at, using R, so the only two websites I've found pertaining to
this issue have been way over my head.  I was hoping for a simple set of
instructions that I could follow to produce a boxplot, in R, for three
groups of data, with 8 weighted responses.  For example, the groups are
three different professions, each asked to fill out and rank 8 statements
in order from 1-8.  Ideally these would be on one graphic output, but if
that can't be done, one output per group would be suitable.

Look at the help for bxp:
?bxp

# The following give you insight into a boxplot structure
bp = boxplot(list(a=rnorm(10),b = rnorm(10), c = rnorm(10)))
bp
