I'm glad you figured it out.
You do still need to reply to the R-help list, not me, but because you
did reply just to me I discovered that your orignal question had an
image in it of your desired result, which was stripped by the
pliant-text R-help server.
So your original email ended with:
"Is there anyway of coding if I could arrange like this?"
with absolutely no way to know what that was referring to.
Please take a look at the posting guide for this list to better
understand how to frame good questions, so people can help you.
