Your wish is reasonable, but note that there are two kinds of default arguments handled by lattice.options(): those that are common for all functions (like "as.table" and "between") and those that are function-specific, like "panel.xyplot", "panel.bwplot", etc. Adding a new default of the second kind involves a lot more work (both implementation and maintenance), and I would be reluctant to do so unless there is a really good reason. I'm more open to additions of the first kind. In this particular case, "default.scales" is really function-specific. On the other hand, only a few functions (e.g., bwplot, cloud, splom) have a default value other than list(), so having a global default (overridden in those few cases) shouldn't be too bad. Of course then it will not be possible to have, say, an xyplot-specific change, because the change will also affect densityplot(), histogram(), etc. If that seems reasonable, please go ahead and send me a patch. -Deepayan > Jim. > > > > Peter Ehlers wrote: >> >> On 2011-03-10 15:07, Jim Price wrote: >> New feature not needed.
