Aren't there methods to calculated means and variances? Did I misunderstood 
that those can be used in Shewart charts? Ofcourse, things might need 
extensions, like a chart plotter...
I have not tested all CRAN modules, but I would have a too positive

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...
