[R-sig-Geo] Help

[Bakary Faty]

Dear,

I'm writing to express my wish to join R-sig-geo list users.
I was doing a search on the net to know how to build an isohyet map and I
came across this R code.
However, I stumbled upon a problem from the line :
grd <- expand.grid(x=seq(minx, maxx, by=pixel), y=seq(miny, maxy,
by=pixel)),
I get the following error message:
default method not implemented for type 'S4'. I want to know how resolve
this error.

Also, I would like to ask you only at the line level:
minx <- rain_data_UTM at bbox[1,1]
maxx <- rain_data_UTM at bbox[1,2]
miny <- rain_data_UTM at bbox[2,1]
maxy <- rain_data_UTM at bbox[2,2],
if I should limit myself to "rain_data_UTM" or write completely:
rain_data_UTM at bbox[,].
 By the way, this is the pointfile I reconstructed.
You can find it attached to the mail.

Thanks in advance

Best regards



Bakary
