[Ubuntu] installing predict-gstat

[Ismaila Diallo]

Dera UBUNTU,

since some times i try to install predict-gstat in an ubuntu 9.1 version but i 
met many difficult. i have also installed R-statistic and when running my R 
script i met an error like: 


"chfactor.c", line 130: singular matrix in function LDLfactor()
Error in predict.gstat(g, newdata = newdata, block = block, nsim = nsim,  : 
  LDLfactor

It's my first time that i get this difficult. so if some have idea in this same 
errors then can he teach me how to resolve it.

Sincerely
Cheers!!!!!!!!
