Greets, My data looks like:
> p3.18 s xbar subgroup 1 0.84 12.2 1 2 1.64 11.2 2 3 2.07 10.6 3 4 2.49 12.2 4 5 0.84 11.2 5 ... Using the command > qcc(p3.18$xbar,type="xbar",sizes=5,center=mean(p3.18$xbar),std.dev=mean(p3.18$s)/0.94,title="X-bar > Chart for Paper Sheet Length Data") I get the x-bar chart I expect. However, using the command > qcc(p3.18$s,type="S",sizes=5,center=mean(p3.18$s),std.dev=mean(p3.18$s)/0.94,title="S > Chart for Paper Sheet Length Data") I get the following error: Error in plot.window(...) : need finite 'ylim' values It seems reasonable that if the first command produces correct results, so should the second. What am I doing wrong?
