geo_vis: Visualise geometric objects

In EhrmannS/geometr: Generate and Modify Interoperable Geometric Objects

Visualise geometric objects

Description

Visualise geometric objects

Usage

geo_vis(
  ...,
  window = NULL,
  trace = FALSE,
  new = TRUE,
  clip = TRUE,
  theme = geoTheme
)

Arguments

...	objects to plot and optional graphical parameters.
window	data.frame(2) two opposing corners of a rectangle to which the plot is limited.
trace	logical(1) Print the provenance information of the geometric object (if available) (TRUE), or simply plot the object (FALSE, default).
new	logical(1) force a new plot (TRUE, default).
clip	logical(1) clip the plot by the plot box (TRUE, default), or plot also objects that go beyond the plot box.
theme	geometr theme the theme from which to take graphical parameters; see geo_theme for details.

Value

Returns invisibly an object of class recordedplot, see recordPlot for details (and warnings).

Examples

# make an empty plot
geo_vis()
geo_vis(window = getExtent(gtGeoms$grid))

coords <- data.frame(x = c(30, 60, 60, 40),
                     y = c(40, 40, 60, 70),
                     fid = 1)
(aGeom <- gs_polygon(anchor = coords))
geo_vis(aGeom)

win <- data.frame(x = c(0, 80),
                  y = c(0, 80))
withWindow <- geomio::setWindow(x = aGeom, to = win)
geo_vis(expanded = withWindow)

(aRaster <- gtGeoms$grid)

# plot several objects together ...
geo_vis(aRaster, aGeom)

# ... and give them names
geo_vis(`a raster` = aRaster, `a geom` = aGeom)

# use graphical parameters ...
geo_vis(aGeom, linecol = "green")

# ... or a theme
geo_vis(aRaster, theme = geo_theme(title = list(plot = FALSE)))
