Dear Simon,
thanks for comments.
I better give a bit of a background first. We are analysing time series of
financial data, often multivariate and with say 200K samples. It is quite a
frequent situation that one needs to display multivariate time series of say
200K rows and 10 columns over

What we need is a more general framework for interactive graphics - this
requires more than just a graphics subsystem - you have to depart from the
concept of graphics objects and include statistical objects in the mix
such that the underlying data/statistics etc. can be identified by linking

Actually, the contours and the smooth are currently printed with
col=2. This prints satisfactorily in grayscale.Colours (orange
and darkred as well as col=2) are also used in termplot.
Does the stricture against colour extend to grayscale? Does it
apply to lines as well as text?
Hmmm, the favorite.

Dear All
I am preparing a number of vignettes that require a very long time to
process with Sweave. The longest one takes 10 hours. I love the weaver
package!
Is a package that includes such a computationally intensive vignette
acceptable on CRAN? Are there any guidelines here?

R lacks functionality that would allow displaying of interactive plots with two

Dear John and Brian,
My point about colour-blindness was partly tongue-in-cheek, but I think that
it's a bad choice to have the second and third colours in the default
