I'm running R version 1.9.0 on Mac OS 10.3.5. I have created text files with data that I need to access from R. When I use the read.table command, I get the warning message: "cannot open file" These text files DO work on a Mac with a previous version of R. I have tried pasting the data into a new text file, but I just can't make a file that the current version of R will open (I have tried this both with Word and with the native OSX text edit program). Am I doing something wrong or is there some incompatibility here? -- = = = = = = = Matthew L Forister Section of Evolution and Ecology 2320 Storer Hall University of California One Shields Ave. Davis, CA 95616 lab phone:(530) 752-2225 = = = = = = = =
