I'm using R 2.0.1 in windows XP (and am not currently subscribed to this mailing list). I have a USGS dataset, a text file with fixed width fields, that includes dates as 6-digit integers in the form yrmoda. I could either read them that way, or with yr, mo, and da as separate integers. In either case, I'd like to convert them to a form will allow plotting other "y" variables against the dates (with correct spacing) on the horizontal axis. I've looked in all the manuals, but didn't find a way to do this. I can copy the data to a spreadsheet, make the conversion there, and then move the data to R, but that's a nuisance. I'd appreciate learning whether there is a way to do this all within R. Thanks. Dave Parkhurst
