Usage

setWindow(x, to, ...)

## S4 method for signature 'ANY'
setWindow(x)

## S4 method for signature 'geom'
setWindow(x, to = NULL)

Arguments

x	the object for which to set a new reference window.
to	any suitable data-structure that contains the minimum and maximum values in x and y-dimension to which the reference window shall be set, see Details.
...	other arguments.

Details

Possible data-structures are

• an object of class Extent,

• an object of class bbox,

• a table with two columns (named x and y) containing the minimum and maximum values for each dimension.

Examples

# create a polygon programmatically
coords <- data.frame(x = c(40, 70, 70, 50),
                     y = c(40, 40, 60, 70))
(aGeom <- gs_polygon(anchor = coords))
visualise(aGeom)

window <- data.frame(x = c(0, 80),
                     y = c(0, 80))
(aGeom <- setWindow(x = aGeom, to = window))

visualise(aGeom)
