xy: Efficient point vectors

In wk: Lightweight Well-Known Geometry Parsing

Efficient point vectors

Description

Efficient point vectors

Usage

xy(x = double(), y = double(), crs = wk_crs_auto())

xyz(x = double(), y = double(), z = double(), crs = wk_crs_auto())

xym(x = double(), y = double(), m = double(), crs = wk_crs_auto())

xyzm(
  x = double(),
  y = double(),
  z = double(),
  m = double(),
  crs = wk_crs_auto()
)

xy_dims(x)

as_xy(x, ...)

## Default S3 method:
as_xy(x, ..., dims = NULL)

## S3 method for class 'wk_xy'
as_xy(x, ..., dims = NULL)

## S3 method for class 'matrix'
as_xy(x, ..., crs = NULL)

## S3 method for class 'data.frame'
as_xy(x, ..., dims = NULL, crs = NULL)

Arguments

x, y, z, m	Coordinate values.
crs	A value to be propagated as the CRS for this vector.
...	Passed to methods.
dims	A set containing one or more of c("x", "y", "z", "m").

Value

A vector of coordinate values.

Examples

xy(1:5, 1:5)
xyz(1:5, 1:5, 10)
xym(1:5, 1:5, 10)
xyzm(1:5, 1:5, 10, 12)

# NA, NA maps to a null/na feature; NaN, NaN maps to EMPTY
as_wkt(xy(NaN, NaN))
as_wkt(xy(NA, NA))
