Crops the frame of a surface plot. Soft deprecated in favor of the arguments xrange and yrange in plotSurface().

ggpLayerFrame(object, xrange, yrange, expand = FALSE)

ggpLayerFixFrame(object)

Arguments

object

An object of class SPATA2 or, in case of S4 generics, objects of classes for which a method has been defined.

xrange, yrange

Distance vector of length two or NULL. If not NULL, specifies the x- and y-range to which the spatial output is cropped. E.g. xrange = c(200, 500) results in the two dimensional space being cropped from x-coordinate 200px up to x-coordinate 500px. If NULL, the original range is used.

expand

Specifies image expansion. An image that is cropped based on an image annotation centers around the image annotation. If expand = 0, the default, the dimensions of the image, that is width/x-axis and height/y-axis, are set to include only the image annotation area and nothing more. Using expand, the cropped image section can be adjusted. See section Expansion of cropped image sections for more information.

Value

ggpLayer*()-functions return lists of ggproto objects that can be added to ggplots via the + operator. In most of the cases they are supposed to be added to plots created with the plotSurface*() family.
