Hi all,

I'm having an issue with maxent() in the dismo library.  I can't get
cumulative outputs to work.  Here's what I'm doing:

#Fit my model

max.out <- maxent(x=raster.stack, p=occurrence.points,
removeDuplicates=TRUE)

#These three lines below all produce meaningful predictive maps:

predict(raster.stack,max.out)
predict(raster.stack,max.out, args = "outputformat=logistic")
predict(raster.stack,max.out, args = "outputformat=raw")


#But this map below is entirely NAs:

predict(raster.stack,max.out, args = "outputformat=cumulative")


#And as a test, this produces an error as it should:

predict(raster.stack,max.out, args = "outputformat=nonsense")


Any insights?

Thanks!!!
