Hi Agus,
In this function, and in all other functions in 'raster', the values
of a new RasterLayer object are written to disk if they cannot be
stored in memory (they are saved in a temporary file that is erased
the next time you load the package). To force writing to disk, and to
a more permanent
Agus,
Please see raster::polygonsToRaster
Let 'p' be a SpatialPolygonsDF. Create an appropriate RasterLayer
object, for example use the extent of the polygons and set the
resolution.
r <- raster(extent(p))
res(r) <- 1
# then:
r <- polygonsToRaster(p, r) # there are additional arguments to c

If what you want is a raster grid storing the value of some attribute
of polygons sampl
Hi?
Is it possible to perform a vector to raster conversion in R,
from SpatialPolygonsDataFrame to a SpatialGrid (providing the final resolution?
In particular, is it possible to do it using package raster?
(I know this can be done using gdal or grass etc, but I'm trying
to find an "only R" sol
