[R-SIG-Mac] Some introductory questions

[Mike Feher]

Great, thank you.  I was following along the tutorial session provided in
the official documentation and I could not make sense of how they were
opening the Michelson-Morely experimental data.  It seemed as if they were
forcing the source file to be read in from some library location, where in
all likelihood, users would prefer to make custom locations.  I will check
into both of your suggestions.  I appreciate the help!

Mike

How to find the demo files is contained in the demo help. Type ?demo

Try using file.choose() to locate files using a dialog and it will return
the full name. Spaces shouldn’t matter provided that everything is enclosed
in quotes. Most people don’t use absolute references. They set the working
directory and then just use the name of the file. See under the Misc menu.
