Evaluate a model for intervals of distances to the nearest point in a reference dataset for presence data and a sample of the absence data selected to have a low spatial sorting bias (obtained with pwdSample).
dcEvaluate(p, a, reference, lonlat=TRUE, binsize=15, predp, preda, model,
predictors, fun=predict)
list with Evaluation objects
two column matrix (x, y) or (longitude/latitude) or SpatialPoints object, for point locations
two column matrix (x, y) or (longitude/latitude) or SpatialPoints object, for point locations
as above for reference point locations to which distances are computed
Logical. Use TRUE
if the coordinates are spherical (in degrees), and use FALSE
if they are planar
postive integer. How many presence points in each distance bin?
