R help - Feb 2006 - Stepwise with AICc

Hi,

I would like to uses AIC.c criterion in stepwise selection. I found some
comments about this issue in R help archives, and it seems that no standard
scripts are available. Except from www.prodsyse.com (stepAIC.c), but,
unfortunately, demanding adaptations for R.

Suggestions on this will be very much appreciated

regards
Flavio Zanini

stepAIC uses extractAIC to calculate AIC.  So all that is in principle 
necessary is to modify extractAIC to return AICc.
