Dear all,
    I get the error when I use maxent.jar:
Error .jcall(mxe, "S", "fit", c("autorun", "-e", afn, "-o", dirout,  : 
  java.lang.NoSuchMethodError: density.Params.readFromArgs([Ljava/lang/String;)Ljava/lang/String;

The details:
I am using the Dism!
 o packag

e.Dismo has a function 'maxent' that communi-

cates with this program(MaxEnt).MaxEnt is available as a stand-alone Java program. 
It is normal when I execute the command :
    "jar <- paste(system.file(package="dismo"), "/java/maxent.jar", sep='')" 
when I execute the function:
        xm <- maxent(predictors, pres_train, factors='biome').
The R show the error.
 
 
Java is correct installed ,version is 1.60._18.
My R version is 2.14.0.
 I don't know how to solve the problem. Will you help me out?
Thank you,all.
