This method allows the addition of a re-scaled pixmap to an existing plot, possibly as a logo, optionally preserving aspect. It may be used interactively with
locator, and is positioned in the coordinate system of the plot region. Since the logo is displayed using
image, it does not yet seem possible to use the function outside this region.
addlogo(x, ...) ## S4 method for class 'pixmap': addlogo((x, px, py, asp = NULL))
- an object of class
- a vector of two x coordinates, or a list with two named elements x and y, such as that returned by
- if px is not a list, a vector of two y coordinates
- if omitted or NULL (default), output respects both y coordinates, if a number greater than zero, aspect is preserved in proportion to the difference between x coordinates, multiplied by asp, and only the first y coordinate is respected.
- potentially further arguments passed to and from methods.
The same pixmap object with changed bounding box and cell resolution
