subset selection for glm

Hello Dhiren,

Hello:

Are there any libraries that will do a subset selection for glm's?  I looked
through leaps, but seems like it is specifically for linear regressions.

?subset should tell you. AFAIK, subset function is not depend on a
special statistical procedure, but on types of datasets: vectors,
matrices or data frames, as the related help page says.

From ?glm help page:

All of 'weights', 'subset', 'offset', 'etastart' and 'mustart' are
     evaluated in the same way as variables in 'formula', that is first
     in 'data' and then in the environment of 'formula'



If you want a more secific answer to your question it would be very
helpful to see a toy example of yours.

The posting guide (at the bottom of every mail ) is very helpful to
set up clear questions which likely increase your chance to get more
helpful responses from the list.
