Source: R/setWindow.R

Set the reference window of a spatial object.

setWindow(x, to, ...)

# S4 method for ANY
setWindow(x)

# S4 method for 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.

Value

The object x with an update reference window.

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.
