Aren't there methods to calculated means and variances? Did I misunderstood
that those can be used in Shewart charts? Ofcourse, things might need

That is why I cross-posted this message to r-devel. Is there interest in such
functionality? At least I am interested, even in coding this extra
functionality, but before doing so, I thought it would be nice to discuss
this on the developers list...

Not that I would like to have the last word, or want to offend you, but I
already wrote my answer before reading this line...
