Q:

Package to use for AICc (Akaike Information Criterion corrected) in r

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. 

A:

Package MuMIn wil calculate it with the function AICc.
