Does anyone know what package to use for AICc (Akaike Information Criterion corrected) in r? I am currently using the package 'MASS' and function 'step' to find the best AIC, but I would like to find the best AICc because my sample size is small.
Thank you in advance.
Package MuMIn wil calculate it with the function AICc.

It is build into the R core stats package. No extra packages need to be installed.
