sfc_point {sfheaders} | R Documentation

## sfc POINT

### Description

constructs sfc of POINT objects

### Usage

    sfc_point(obj, x = NULL, y = NULL, z = NULL, m = NULL)

### Arguments

`obj` | sorted vector, matrix or data.frame
`x` | x geometry column
`y` | y geometry column
`z` | z geometry column
`m` | m geometry column

### Value

`sfc` object of POINT geometries

### notes

sfheaders functions do not perform any validity checks on the geometries. Nor do they set Coordinate Reference Systems, EPSG, PROJ4 or precision attributes.

The data.frame and matrices you send into the sfheader functions must be ordered.

### Examples

    x <- c(1:3)
    sfc_point( x )

    x <- matrix( c(1:10) , ncol = 2 )
    sfc_point( x )

    x <- setNames( as.data.frame( x ), c("x","y") )
    sfc_point( x )
    sfc_point( obj = x, x = "x", y = "y" )
    sfc_point( obj = x, x = "y", y = "x" )
