Returns a character vector of NE, SE, SW, NW corresponding to north-east, south-east quadrants respectively. If number_out is TRUE, returns numbers from 1:4, respectively.

Usage

quadrant(x, cent = NULL, number_out = FALSE)

Arguments

x

Object of class sf

cent

The centrepoint of the region of interest. Quadrants will be defined based on this point. By default this will be the geographic centroid of the zones.

number_out

Should the result be returned as a number?

Examples

x = zones_sf
(quads <- quadrant(x))
#> Warning: st_centroid assumes attributes are constant over geometries of x
#> [1] "SE" "SW" "SE" "NE" "NE" "SW" "NW" "SE"
plot(x$geometry, col = factor(quads))
