[R] unexpected error message with variog.mc.env() - geoR

[Patrick Giraudoux]

Dear R-listers,

I have got an error with variog.mc.env() package:geoR that I cannot sort 
the origin out.  The origianal data file can be sent to people interested.

bin0<-variog(don1bgeo,estimator.type="modulus",  direction=0)
bin90<-variog(don1bgeo,estimator.type="modulus",  direction=pi/2)
env.variog0<-variog.mc.env(don1bgeo,obj.variog=bin0)
env.variog90<-variog.mc.env(don1bgeo,obj.variog=bin90)

everything goes smoothly with bin90, but using bin0 gives this error
after permutations:

 > Error in variog.mc.env(don1bgeo, obj.variog = bin0) :
         (subscript) logical subscript too long

Any idea about what happens?

Regards,

Patrick
