[R-sig-eco] Query related to maxent file in dismo package

[Francisco Rodriguez Sanchez]

Dear Rajendra,

Are you running the 64-bit version of R? In that case I think you will 
need to install the 64-bit version of Java as well, or alternatively 
switch to the 32-bit version of R to run these analyses (that is what I 
did when I had this same problem).

Try loading rJava (and dismo) with the 32-bit R version - does it work?

Hope it helps,

Paco
