Hello!
 
I have a text file that looks like
 
ew;ns;cures
1394180;6200295;48
1398190;6201020;52
1399690;6200420;59
1395780;6205105;84
1397820;6206590;50
1395290;6208305;46
1394995;6210370;114
1399475;6213715;92
1410825;6214870;48
and so on
I manage to interpolate with 
 
sn8.interpold <- interp.old(ew, ns, cures,
              xo= seq(min(ew), max(ew), length = 400),
              yo=seq(min(ns), max(ns), length = 300),
              ncp = 4, extrap=FALSE, duplicate = "error", dupfun = NULL)
then I want to crate a asciigrid...
write.asciigrid(sn8.interpold,"asciisn8", na.value = -9999)
and here I got problems...
Any tips?
 
Thanks Mikael
