All, I'm having a problem selecting directly from a vector. I've written ways to do this indirectly, but I'd rather do it directly and didn't see this in the manual. Essentially, I have:
group.label.new
[1] 7 9 6 1 10 4 8 3 2 5
junk
[1] 1 2
group.label.new[junk && 8:10]
[1] 7 9 6 1 10 4 8 3 2 5 I'd like to select the elements indexed by "junk" and also the 8th through 10th elements, which clearly isn't the result I'm getting. Any help appreciated, and please reply directly to afshar at miami.edu cheers, dave [[alternative HTML version deleted]]
