There are several packages available for analysis of distance sampling data:
Distance- this package! An easy interface tomrds.mrds- the package incorporated into the Windows application Distance (since it supports many features, the syntax can be rather tricky for beginners).unmarked- uses the hierarchical modelling approach of Royle et al (2004).Rdistance- can be used to perform CDS analyses.
This table provides a feature comparison of the packages:
