Is there an elegant way in R to change a number reported as a less-than number in text format, "<1" for example, to the numeric equivalent 1? I have been trying to use as.numeric, but have not come up with anything clever yet. Tom

Dear Tom, I don't know whether it qualifies as elegant or clever, but you should be able to use sub(), as in
as.numeric(sub("<", "", c("1", "< -2", "<1")))
