I have a data.frame named "df". The dput of df is at the bottom of this e-mail. What I'd like to do is replace the "n/a " values with NA. On Mac OSX, it works to do this: df[df == "n/a"] <- NA However, it does not work on Ubuntu. See below.

Is that exactly what you're doing, in a clean session? x <- rdata[27, 4]> x == "n/a "[1] TRUE> x == "n/a"[1] FALSE Because as long as the space is included, the test should be TRUE. (I renamed the dput object rdata, because df() is a base function.) df[df == "n/a"] <- NA shouldn't work on Mac, or any other system, because no elements of your data frame are "n/a", but are instead "n/a " If it were my data, I'd get rid of the spaces at the end of the values before trying to do anything, either before reading it into R, or with gsub() after.

"n/a?" == "n/a\uA0" [1] TRUE "n/a\uA0" [1] "n/a?" Hope this helps. Petr Savicky.

On my system that's what happens. Is this still repeatable in a new session? If so, can you show us what you get from charToRaw? I get > charToRaw(x) [1] 6e 2f 61 20 but perhaps you have some different character in the fourth position, one which just happens to display as a space. If it is not repeatable in a new session, then it's hard to guess what went wrong, but conceivably memory corruption somewhere could have caused this. It would be worthwhile keeping track of what you were doing if it ever happens again.
