[R] suppress plot w/ ewma function from qcc pkg

[Francis, Brian]

Hi,

I've been searching for a solution to this but have come up empty.

I would like to suppress the plot creation when using the ewma function
in the qcc package.  Normally it's just plot = FALSE, but the ewma
function doesn't have this option.  Anything I'm missing or a work
around?

Many thanks,
