Thank you very much Robert,
Now I have this error:
> me <- maxent(bio1res, arb)
Error en .local(x, p, ...) :
more than half of the presence points have NA predictor values
It could be related to the raster "bio1res"? The origin of this file is
.bil files. Which is the best file format to work with bioclim data?
The plot(bio1res) display with a legend with values from 0 to 50000 and
the raster is for temperature.
bio1res
class : RasterLayer
filename :
nrow : 382
ncol : 407
ncell : 155474
min value : 47
max value : 55537
projection : NA
xmin : -85.95
xmax : -82.55833
ymin : 8.041667
ymax : 11.225
xres : 0.008333333
yres : 0.008333333
Best,
Manuel
