[R] TukeyHSD error

All - I think I'm being dense, but for the life of me, I can't figure out why I get error message with the code below. I have data that looks like param level perc.surv asin.tran DO 3 0.6864407 0.9764544 DO 3 0.125 0.3613671 DO 3 0.8738739 1.2077299 DO 4 0.4615385 0.7468986

Re: [R] TukeyHSD error

Rescinded. Problem solved. I discovered that TukeyHSD doesn't like numeric factors; changing the level to a factor solved my problem. SR Steven H. Ranney steven.ran...@montana.edu __ R-help@r-project.org mailing list
