shape2Grid: Function to create a grid given a spatial polygon

shape2Grid creates a raster grid given a spatial polygon and a grid resolution.

Usage

shape2Grid(shpolygon, resolution, ones = TRUE)

Arguments

shpolygon: A SpatialPolygon, SpatialPolygonDataFrame representing the desired shape of the grid.
resolution: Numeric. Spatial resolution of the grid.
ones: Logical. Fill with ones the values of the raster. If not the values will be written as cellID values.

Value

Returns a raster object with the shape of 'shpolygon' of a given resolution.

xy <- cbind(x_coord, y_coord)
p <- sp::Polygon(xy)
ps <- sp::Polygons(list(p),1)
sps <- sp::SpatialPolygons(list(ps))
r1 <- bamm::shape2Grid(sps,resolution = 0.1,ones = FALSE)
plot(r1)
sp::plot(sps,add=TRUE)
