[R] Filling in a Zero Matrix

[Julian Burgos]

My mistake, by xlabel and ylabel you are refering to the row and column 
names of your matrix, right?  To label a matrix you can simply use 
colnames() and rownames().

Still its not clear to me what you are trying to do with your code. 
Perhaps if you give us a sample of your data and explain clearly what 
you are trying to achieve, we can help you to simplify your code.

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.
