Thanks for those on the list that answered my previous question. I'm just about where I need to be (looking at output). In the hier.part documentation there is a line env <- urbanwq[,2:8]. This means use rows 2 through 8 in the data frame "urbanwq", right? What does the comma represent? If one wasn't using column headers would this be necessary? Thanks, Jeff **************************************** Jeffrey A.

Hi, Jeff,
Actually it means *columns* 2:8. See the documentation and examples in
help("[").
