Let's say that the vector you are calling `as.numeric` over is called `x`. If you could show us the output of the following command: R> head(x[is.na(as.numeric(x))]) You'll see why you are getting the warning. How you choose to sort it out probably depends on what you are trying to do with your data after you convert it to a "numeric" -steve -- Steve Lianoglou Computational Biologist Genentech ______________________________________________ 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.
