Thank you Peter and Jorge,

Hi R-users,
I would like to do looping for this process below to estimate alpha beta from
gamma distribution:
Here are my data:

Hi,
I'm very new to R and absolutely love it. Does anyone know how to use
something in R that functions like a BY command in SAS?
For example, let's say you have a variable x, and you want to see the mean.
Easy...

But what if you want to see the mean of x conditional on another disc

Tom,
Yes, just re-execute JGR-15.exe (I assume your are on windows & downloaded
the latest version). Window's explorer search should find it.
For convenience, I make a shortcut on my desktop pointing to JGR-xxx.exe.

Normally in R one returns a list and assigns that to a single
