Usage

broennimannEcospat(native_stack, invasive_stack, native_occ, invasive_occ,
  kept_axes = 2)

Arguments

native_stack	A raster stack of the environmental data for the range of the native species.
invasive_stack	A raster stack of the environmental data for the range being invaded
kept_axes	The nf parameter in the function dudi.pca - is the number of kept axes - defaults to 2.
natice_occ	Occurence points for the native species (i.e. where the species that will be invading into the invasive range is in it's native range). A two-column matrix with column headings x and y (corresponding to longitude and lattitude)
