Package: alien 1.0.2.9000

alien: Estimate Invasive and Alien Species (IAS) Introduction Rates

Easily estimate the introduction rates of alien species given first records data. It specializes in addressing the role of sampling on the pattern of discoveries, thus providing better estimates than using Generalized Linear Models which assume perfect immediate detection of newly introduced species.
