Package: latbias Type: Package Title: Calculate the Latitudinal Bias Index Version: 1.0.0 Authors@R: c( person("Pierre", "Denelle", email = "pierre.denelle@gmail.com", role = c("aut", "cre"), comment = c(ORCID = "0000-0001-5037-2281")), person("Pieter", "Sanczuk", email = "Pieter.Sanczuk@UGent.be", role = c("aut" ), comment = c(ORCID = "0000-0003-1107-4905")) ) Description: Studies that report shifts in species distributions may be biased by the shape of the study area. The main functionality of this package is to calculate the Latitudinal Bias Index (LBI) for any given shape. The LBI is bounded between +1 (100% probability to exclusively record latitudinal shifts, i.e., range shifts data sampled along a perfectly South-North oriented straight line) and -1 (100% probability to exclusively record longitudinal shifts, i.e., range shifts data sampled along a perfectly East-West oriented straight line).
