[Biomod-commits] discrepancies

[Wilfried Thuiller]

That means your dbf files is half empty.

There are different ways to deal with the problem:

Either you save the data from Arcgis as txt file and then you read the  
txt file. It should work nicely.

Or you save the date in shapefile and then load the data in R using  
spatial package
For instance

library(rgdal)
My.Data <- readOGR("path_to_the_right_folder",  
layer="name_of_the_files_without_extension")
summary(My.Data)
#Check out the data as they will encapsulated in the OGR object.
Type to see where they are:
str(My.Data)
