[R] Filling in a Zero Matrix

[Julian Burgos]

Hi Amy,
Many (perhaps most) of the people on the list do not receive emails with 
html...so we can't see colored text.  Also it would be helpfully to have 
a bit of your data, so we can run your code (see the posting guide in 
this regard,http://www.R-project.org/posting-guide.html).

Please explain what are the 'xlabel' and the 'ylabel' that you 
mentioned.  I don't see those variables in your code.

Julian

I am now trying to fill the matrix. There seems to be some problem with this section of my code. I have highlighted the dodgy code in red. Please help if possible.
