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
#> [1] "SE" "SW" "SE" "NE" "NE" "SW" "NW" "SE"
plot(x$geometry, col = factor(quads))
