I am trying to do some kriging job, after a longer time. It looks that there is an error, but I am not sure where is it. I got a following error message

Error in parse(file, n = -1, NULL, "?", srcfile, encoding) :
  R_temp: syntax error, unexpected NUM_CONST, expecting ',' at
22: ,vgm(psill=4,model="Sph",range=800,nugget=))
23:
Execution halted
Done

Could somebody help me?

Many thanks in advance

Having not used the script I would suggest a couple things:

1. check your region: kriging requires A LOT of matrix inversions, and thus
becomes memory limited with large regions.

2. you might try the commands one at a time in order to pin down the errors

Here is a link to a kriging example using grass vector data as the input, with
R+GSTAT (not sure what v.surf.krige uses ...)
