This package provides some functions used internally by the spatial capture-recapture package secr (from version 5.4.0). The idea is to speed up the installation of secr, and possibly reduce its size. Initially the functions are those for area and transect search that use numerical integration code from RcppNumerical (Qiu et al. 2023) and RcppEigen.
The functions are not intended to be user-friendly and require considerable pre-processing of data. Examples and tests use data pre-formatted and saved in the 'extdata' folder.
