Thank you Roman and Johannes,
What I am doing wrong?
x <- readGDAL("bio1_23.bil")
xr = raster(x)
map <- readOGR(dsn="C:/ProyectoRespacial/EvalHab_reporte",
layer="Cr_wgs84_meso") # shapefile
> r2 <- polygonsToRaster(map, xr)
Found 1 region(s) and 1 polygon(s)
Error: no se puede ubicar un vector de tamaño 98.9 Mb
Best,
Manuel
