This is a question I got via email: how do you remove occurrence points from the suitability plots that are spit out by ENMTools modeling functions?
Luckily this is quite easy, as these are just ggplot objects.
mont.mx <- enmtools.maxent(iberolacerta.clade$species$monticola,
euro.worldclim, test.prop = 0.3)
with.points <- plot(mont.mx)
without.points <- remove_geom(with.points, "point", 1:2)
