[R-sig-Geo] connection error when calling maxent()

[rafael.wueest]

Hi Folks

when I am trying to call the maxent() function within a function I created,
I am getting the following error:

Error in file(con, "r") : cannot open the connection
In addition: Warning message:
In file(con, "r") :
  cannot open file
'/var/folders/ft/fthJYD+6GkCvmcCArZBaQU++waU/-Tmp-/R_raster_tmp/maxent/10943312360/species.lambdas':
No such file or directory

I am here also pasting some output of
>traceback()
7: file(con, "r")
6: readLines(paste(dirout, "/species.lambdas", sep = ""))
5: unlist(readLines(paste(dirout, "/species.lambdas", sep = "")))
4: .local(x, p, ...)
3: maxent(background, occ, args = me.args) at run4models_restios.r#558
...

I am using JGR on a Mac and downloaded the newest dismo (CRAN sources) and
maxent version (see below). 

Can anyone help me? I am happy to provide more detailed information...

Rafa
