Duncan, Thanks for the help.
I'm new to R, so I'm not sure how to get R to round the values and "group" them into larger blocks. I have tried the following: xlim=seq(0,2000,100),ylim=seq(0,2000,100) just to see if it would work, but it doesn't... Do you think you might be able to explain how to go about rounding the values?
