Simple Interfaces to modify Trellis Settings

Description

A (hopefully) simpler alternative interface to trellis.par.get/set. NOT S-compatible

Usage

lset(theme, warn = TRUE)
col.whitebg()

Arguments

theme a list decribing how to change the settings of the current active device. Valid components are those in the list returned by trellis.par.get(). Each component must itself be a list, with one or more of the appropriate components (need not have all components). Changes are made to the settings for the currently active device only.
warn logical, whether a warning should be issued when trellis.par.get is called when no graphics device is open

Details

lset essentially does the same thing as trellis.par.set, but is different in that it allows setting more than one parameter at a time, and also that each component need have only the components that need to be changed.

This function is expected to be used mostly in conjunction with functions that return `themes', i.e., lists which when supplied to lset change the overall look and feel of the display.

col.whitebg is one such function, which returns a list which when supplied to lset changes the background to transparent and the other colors to something suitable. Contributions of more such `themes' are welcome.
