mcp: Minimum Convex Hull Polygon
| mcp | R Documentation |
Minimum Convex Hull Polygon
Description
Generates a minimum convex polygon (MCP; i.e., convex hull) that is delineated from occurrence locality coordinates. This function is a wrapper for 'chull()' that makes a SpatialPolygons object.
Usage
mcp(xy, crs = NULL)
Arguments
xy |
Matrix or Data frame of occurrence coordinates |
crs |
Character of coordinate reference system for minimum convex hull |
Value
a SpatialPolygons object of the minimum convex hull around occurrences.
Examples
# generate occurrences
ras1 <- raster::raster(nrows=108, ncols=108, xmn=-50, xmx=50)
raster::values(ras1)<- runif(n = (108*108))
occs <- dismo::randomPoints(ras1, 4)
# create mcp
mcp(occs)
