Welcome to r-sig-geo! I don't think that you haven't provided us enough information so that we can help. On the other hand, does the example below using expand.grid help?
minx <- 20 maxx <- 25 miny <- 31 maxy <- 36 pixel <- 1 grd <- expand.grid(x = seq(minx, maxx, by=pixel), y = seq(miny, maxy, by=pixel)) Ben On Thu, Jan 9, 2020 at 11:41 AM Bakary Faty <bakaryf...@gmail.com> wrote: > > 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'.
