Spatially explicit capture-recapture CRAN Task View: Environmetrics (http://CRAN.R-project.org/view=Environmetrics) Functions to estimate the density and size of a spatially distributed animal population sampled with an array of passive detectors, such as traps, or by searching polygons or transects. Models incorporating distance-dependent detection are fitted by maximizing the likelihood. Tools are included for data manipulation and model selection.
