axes tick labels

[Paul Matthias Diderichsen <paulmatthias.diderichsen@abbott.com>]

Dear S-plus Gurus,
somebody asked me to do a xyplot of
some data versus time. No problem, I said. Then, they told me that the
ticks and labels along the time axis (abscissa) were to be multiples of
24 (hours). No problem, I repeated, anticipating none. But - alas - it
did turn out to be a problem.

Please let me know if you have any ideas
how to accomplish this - dirty workarounds are accepted. ;-) Also please
tell me, if you are relatively sure that this can not be done. More generally,
I am looking for a solution similar to matlab's XTick=[vector of positions
on the axes where ticks are to appear] and XTickLabels={array of strings}.


Thanks a lot, Paul M. Diderichsen.
