col.whitebg()

Details
lset is a wrapper to trellis.par.set that allows setting
more than one parameter at a time, and only the components that are to
be changed need be specified.
This function is expected to be used 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.
lset is used to modify the settings on a one-time basis. It is
also possible to make persistent changes in the default theme used via
a user-settable option, see trellis.device for details.
show.settings(col.whitebg())
