More context would be useful, but my first guess is that you are running into problems because both file and append are functions. If you didn't explicitly set them to something else, R is using the function.
What happens if you instead use: filename <- "myfile.csv" toappend <- FALSE file(filename, ifelse(toappend, "a", "w")) Sarah On Fri, Sep 17, 2010 at 12:02 PM, lord12 <gaut...@yahoo.com> wrote: > > I get an error message: > > Error in file(file, ifelse(append, "a", "w")) : invalid 'open' argument > > How do I resolve this? > -- -- Sarah Goslee http://www.functionaldiversity.org ______________________________________________ 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.
