lset: Simple Interfaces to modify Trellis Settings
Description
A (hopefully) simpler alternative interface to
trellis.par.get/set. NOT S-compatible
Usage
lset(theme)
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 (
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.
show.settings(col.whitebg())
