[R] Subsetting a square marix

[Sarah Goslee]

It really isn't clear what you want, and posting in HTML has mangled
what you did provide.

Please use dput() to provide sample data, and give us a clear idea of
what you want, ideally an example of what the output should look like.
Adding the R code you've tried to use is also a good idea.
