project_maxent
uses feature weights described in a .lambas
file or MaxEnt
object to predict a Maxent model to environmental
data. This function performs the projection entirely in R, without the need
for the Maxent Java software. For tested datasets, it performs the
projection in roughly one third of the time taken for the same projection
by maxent.jar.
If newdata
is a RasterStack
or RasterBrick
, a
list with two elements:
prediction_raw
: a Raster
layer giving the raw Maxent
prediction; and
prediction_logistic
: a Raster
layer giving the
logistic Maxent prediction.
If newdata
is not a RasterStack
or RasterBrick
,
the raster layers will be replaced with data.table
s in the returned
list.
This function is still in development, and no guarantee is made for the accuracy of its projections.
