You need to create some grouping for your cut points (0-100, etc). See ?cut
Then, you can use boxplot and formula (y ~ NEWVARIABLE from cut) boxplot(y ~ cut(x)) There may be other ways to do this, but the above should work.

My apologies if anyone is seeing this twice...looks like my previous message didn't come through... Dear UseRs, I have a feeling this is a relatively simple question, but I'm having a hard time getting my head around it. I have a simple x-y scatterplot with many points, as shown below(attached). I'd like to make a boxplot of this by interval, such that there is one box representing the points in the 0-100 interval, one for the 101-200 interval, and so on. How do I structure my R data frame to be able to generate such a boxplot?
