I'm trying to do it with pie(), and I want to have just the plain pie-chart with no annotations. So far so good: "labels=rep(NA,...)" will do it. But I want to have it output to an EPS file with the

I have been having the same problem as poster Hodgess, below. It appears that her question was never answered, so I would like to share a solution with the community. The problem is the (apparent?) inability to produce moving range process behavior (a.k.a. "control") charts with individuals data in the package "qcc" (v. 2.0).

You may want to rethink your whole approach here: 1. Pie charts are usually a poor choice of graph, there are better choices. 2.
