[R] plotting box plots on same x

[BJ]

Does it matter what they are? they are just names. The six box plots are 
from the array I created with columns. I forgot to add teh dim 
statement, my mistake. But I thought it was obvious that i was using a 
matrix from the data frame call and the assignments I provided. My 
question was simply about setting the x axis so that it stopped after 
x=3, even though I had 6 plots.  For teh record, before I get jumped on 
for the statistics, I am just using a 3 x 6 matrix to test the code 
before applying it to actual data. Also, I was not being scarcastic. I 
have recieved a lot of help from this mailing list. The R documentation 
is hard to hunt down and not complete. Without the help of actual people 
I would be dead in the water. I am sorry for any hostility that I have 
incurred. ~Erithid
