rsgeo (version 0.1.7)

geom_point: Construct Geometries

Description

Constructs geometries from numeric vectors.

Usage

geom_point(x, y)
geom_multipoint(x, y, id = 1)
geom_linestring(x, y, id = 1)
geom_polygon(x, y, id = 1, ring = 1)
geom_line(x, y)

Value

an object of class rsgeo

Arguments

x

a vector of x coordinates

y

a vector of y coordinates

id

the feature identifier

ring

the id of the polygon ring

Details

In the case of geom_line(), both x and y are vectors of rs_POINT geometries. geom_line() creates a straight line between two points.

Examples

geom_point(3, 0.14)
geom_multipoint(1:10, 10:1)
geom_linestring(1:10, 10:1)
geom_polygon(c(0, 1, 1, 0, 0), c(0, 0, 1, 1, 0))
x <- geom_point(0, 0)
y <- geom_point(5, 0)
geom_line(x, y)
