No reaction so far....
I've realized that I can introduce this very easily into
plot.lm():
Instead of the former argument
panel = points
I use the new ones
panel = if(add.smooth) panel.smooth else points,
add.smooth = isTRUE(getOption("plot.add.smooth")),
- - -
Now I even propose to have
options(add.smooth = TRUE)
as a new default.....
Do I get a reaction now?
I like the name "add.smooth" (as used at the bottom) better
than "plot.add.smooth" (as used a few lines up).
With that choice, I think it's a good idea.
