Re: [R] convert to csv file
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.

Re: [R] convert to csv file
Hi: The first argument of ifelse is a logical statement that must evaluate to either TRUE or FALSE. I'm guessing that you're using the append function here, which is not a logical statement. Perhaps it would help if you described what you wanted to do with a reproducible example to illustrate the problem.

Re: [R] convert to csv file
I might add that ifelse() is a vectorized function - is the operation you're trying to perform vectorized? D.

In order to use the extension csv, is the syntax: write.table(table_list, file= paste(file, x, sep = ).csv, sep = ,) ?
