Please reply to all so the thread stays on the mailing list for all to see (and correct if wrong information is given).

Regarding your code below, either you are missing a library statement to load a package that contains this "trial" data, or you are intending to read in your own data set but are not yet aware of how that is done.

I could find no package containing a data set named "trial" (but I might have missed one). 

If you have some data of your own, then the data function is almost certainly not the right tool for the job. A PDF document called "R Data Import/Export" is supplied with R that can get you started. There are also various intro books available.
