Submission from: (NULL) (76.240.79.123)
I downloaded the most recent version of R for the mac (About: GUI 1.22-devel
(4859) (4859)) and installed it.
After installation, I opened the help file and ran the demo. I am new to R,
although I have over 25 years experience in SAS.
Below is a part of the job I ran. I think I ran the code correctly, but I seem
to be blowing off.
And, I'm not sure it's related, but I also included what I got when I ran
bug.report()
> dummy <- data.frame(x=x, y =x+rnorm(x)*w)
> dummy
