Not without Fall.dat I suspect. please read the posting guide and act accordingly. (And why post twice?) I suspect some of your data are missing in Fall.dat (or end up missing because you didn't check what had been read in by R) and that this has propagated warnings in say mean, when called within na.rm = TRUE. But I'm guessing as you fail to provide a reproducible example. Why this is different between Unix/windows versions of R, I don't know, but are they running the same versions of R?
