Thanks to Michael, Josh and Jorge - Problem fixed. Michael's suggestion was what I needed, but I wouldn't have ever conceptualized it that way, and Jorge showed me how simple the function could be (at this hour, I was imagining it would be more work). Thanks guys. Bryan On 11/28/1

[R] Replacing several rows of a matrix at once

mn and recycles vec. What I want to do is replace multiple rows simultaneously at once. I suppose I can write a function, but this seems pretty fundamental so I feel I must be missing some obvious alternative. I'm feeling like I'm in the Inferno! TIA. Bryan * Bryan Hans
