Hi,<br><br>I am using BioMod version 1.1-3 and R version 2.9.2. I suppose I should update these versions?<br>The following is what I typed into R to run the models and the error message I recieved. Also I have listed the summary of my data. Occurance is just the name of the column with my 0/1 info on species data. <br>
