Hello list-mailers,
I'm trying to use the 'Tps' function from the 'fields' package and I can
getting this error message:

> fishplot <- Tps(nodes.catch, res2)
Error in if ((il > 1) & (il < nstep.cv)) { :
        missing value where TRUE/FALSE needed
In addition: Warning message:
no non-missing arguments to min; returning Inf

nodes.catch is a 1600x2 matrix and res2 is a 1600 long vector. They both
contain zeros but no missing values or NA. I really appreciate your help.
Thanks,
Tania
