ElevDistr is a method to calculate the distance to the climatic tree line for large data sets of coordinates (WGS 84) with geographical uncertainty. This R package was developed in the context of the article "Avoiding impacts of phylogenetic tip-state-errors on dispersal and extirpation rates in alpine plant biogeography". For citing this package see below. The default thresholds and the treeline definition is based on Paulsen and Körner, Alp.
