[Biomod-commits] Question about: Error in if (a != "NA") if (a > 0)

I am trying to run the models for biomod but I am getting the following

Error in if (a != "NA") if (a > 0) { :
  missing value where TRUE/FALSE needed

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!
