sfc MULTIPOINT
Description
constructs sfc of MULTIPOINT objects
Usage
sfc_multipoint(
obj,
x = NULL,
y = NULL,
z = NULL,
m = NULL,
multipoint_id = NULL
)
Arguments
obj |
sorted matrix or data.frame |
x |
x geometry column |
y |
y geometry column |
z |
z geometry column |
m |
m geometry column |
multipoint_id |
column of ids for multipoints |
Value
sfc
object of MULTIPOINT 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 <- matrix( c(1:4), ncol = 2 )
sfc_multipoint( x )
x <- data.frame( id = 1:2, x = 1:2, y = 2:1 )
sfc_multipoint( x )
sfc_multipoint( x, x = "x", y = "y" )
sfc_multipoint( x, x = "y", y = "x" )
sfc_multipoint( x, multipoint_id = "id", x = "x", y = "y")
