Dear all, Just to let you know that thanks to your help, I've managed to solve it. For future reference, if anyone's interested (!), if you're having problems reading R-generated data from a Mac, into ArcMap on a PC, then ensure that you're using eol="\r\n" in the write.table command and that you don't have factor or character data when they're really meant to be numeric! To overcome the latter, I did: mrunoff$Longitude <- as.numeric(levels(mrunoff$Longitude))[mrunoff$Longitude] Hope this is of use to someone, somewhere, someday! Thanks again for your advice, Steve _________________________________________________________________ Got a cool Hotmail story? Tell us now
