Try: x[which(is.na(x)),] - 000/000, where is x is your data frame - Lanna Jin lanna...@gmail.com 510-898-8525 -- View this message in context: http://r.789695.n4.nabble.com/How-to-replace-all-NA-values-in-a-data-frame-with-another-not-0-value-tp2125458p2125464.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

000/000 returns NaN, which is no different than NA unless you want it as string i.e. 000/000 Muhammad Lanna Jin wrote: Try: x[which(is.na(x)),] - 000/000, where is x is your data frame - Lanna Jin lanna...@gmail.com 510-898-8525 __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Hi Nevil, You can try a method like this x - c(rnorm(5),rep(NA,3),rnorm(5)) # sample data dat - data.frame(x,x) # make sample dataframe dat2 - as.matrix(dat) # conver to matrix y - which(is.na(dat)==TRUE) # get index of NA values dat2[y] - 000/000 # replace all na values with 000/000 Muhammad Nevil Amos wrote: I need to replace NA occurrences in multiple columns in a data.frame with 000/000 how do I achieve this?

Thanks, this works, replacing the NA values with the 000/000' string.
