R help - Aug 2010 - how to display delta AIC of all models

Dear all,

I am making model selection of generalised linear models based on delta
AIC,
using the command step(AIC).

Also, I would like to learn the explanatory powers of each independent
variable.
To phrase differently, it is in need to show the delta AIC of all models
rather than the final model with the least delta AIC.

Please kindly advise if it is possible to exhibit all delta AIC of different
combinations of the independent variables.
Thank you.

Elaine

  The MuMIn and AICcmodavg packages might be useful.
