The pupR package is a R-package for estimating the pup production of harp and hooded seals in the West Ice (along the coast of Greenland). Abundance estimation of other populations is possible as long as similar input data is available. The package fits available (photographic) count data (from aerial photos) and estimates the abundance of the population of interest. Any type of count data can be used to estimate the abundance or total numbers for a specified area.
Instructions on how to use pupR is found in the vignette.
