plot.wk_wkt

Plot well-known geometry vectors

Description

Plot well-known geometry vectors

Usage

## S3 method for class 'wk_wkt'
plot(
  x,
  ...,
  asp = 1,
  bbox = NULL,
  xlab = "",
  ylab = "",
  rule = "evenodd",
  add = FALSE
)

## S3 method for class 'wk_wkb'
plot(
  x,
  ...,
  asp = 1,
  bbox = NULL,
  xlab = "",
  ylab = "",
  rule = "evenodd",
  add = FALSE
)

## S3 method for class 'wk_xy'
plot(x, ..., asp = 1, bbox = NULL, xlab = "", ylab = "", add = FALSE)

## S3 method for class 'wk_rct'
plot(x, ..., asp = 1, bbox = NULL, xlab = "", ylab = "", add = FALSE)

## S3 method for class 'wk_crc'
plot(x, ..., asp = 1, bbox = NULL, xlab = "", ylab = "", add = FALSE)

Arguments

`x`	A `wkt()` or `wkb()` vector.
`...`	Passed to plotting functions for features: `graphics::points()` for point and multipoint geometries, `graphics::lines()` for linestring and multilinestring geometries, and `graphics::polypath()` for polygon and multipolygon geometries.
`asp`	Passed to `graphics::plot()`
`bbox`	The limits of the plot in the form returned by `wkt_ranges()`.
`xlab`	Passed to `graphics::plot()`
`ylab`	Passed to `graphics::plot()`
`rule`	The rule to use for filling polygons (see `graphics::polypath()`)
`add`	Should a new plot be created, or should `x` be added to the existing plot?

Value

The input, invisibly.

Examples

# requires the wkutils package
if (requireNamespace("wkutils")) {
  plot(as_wkt("LINESTRING (0 0, 1 1)"))
  plot(as_wkb("LINESTRING (0 0, 1 1)"))
}
