plotExtent: Create spatial polygon same size as a plot

Description

This function creates a "rectangular" SpatVector object with the same dimensions as a plot window. It is especially useful for cropping subsequent rasters or vector objects to the plot window. A plot must be made before calling this function.

Usage

plotExtent(x = NULL)

Value

SpatVector

Arguments

x

Either NULL (default), an object of class crs, a coordinate reference string (PROJ6 WKT string), or an object with a coordinate reference system. If any of these is provided, the SpatVector object will have this CRS.

data(mad0)
plot(st_geometry(mad0))
outline <- plotExtent(mad0)
plot(outline, col='cornflowerblue', lty='dotted')
plot(st_geometry(mad0), add=TRUE)

}
