You should read the posting guide again (at all?). Among other things, it suggests you should show what you have tried doing that did not work (worst case it shows us you tried to figure it out on your own before asking other people to freely give their time to solve your problems, at best case, we only need to minimally tweak your code to get you up and running and save time duplicating what you already did that was close to right but not quite). Did you try anything to get 1 to 65 in x and 66 to 130 in y?
Look at the documention for the extraction operator, which you can access by typing at the console: ?"[" ? typically brings up documentation, though you normally do not need to quote function names, [ is special so it needs quotes around it. By leaving the row index empty (that's the part before the comma), you are selecting all rows. If you only want to select rows 1 to 65, try: 1:65 which suggests normtemp[1:65, 1] normtemp[66:130, 1] finally leading us to: x <- normtemp[1:65, 1] y <- normtemp[66:130, 1] Thank you for indicating the package you are using and providing an easy data example, though. I hope this helps. Cheers, Josh On Tue, Oct 11, 2011 at 10:58 PM, JohnnyJames <penguinrule1...@aim.com> wrote: > I am using the normtemp data set in UsingR package.
