Dear All,
Thanks for your inputs. I did replace pointsToRaster () with
raster::rasterize(). Below is part of my script.

But I got another error:
Error in (function (classes, fdef, mtable)  :
  unable to find an inherited method for function ‘rasterize’ for
signature ‘"RasterLayer", "matrix"’

Thank you for more inputs.



w = map("world")
 wc = cbind(w$x, w$y)
 write.table(wc, file = "my.fileb", sep=" ",row=FALSE,col=FALSE)
 rena = function(X,Z){
