Hi,<br><br>I am trying to run the models for biomod but I am getting the following error:<br><br>Error in if (a != "NA") if (a > 0) { : <br> missing value where TRUE/FALSE needed<br><br><br>I am not sure where to start in troubleshooting this error. Is it a problem with my data or with the commands I used to run the models? What do a and NA stand for? Please help!<br>
