the distribution of relative range for estimating sigma, which is

I don't really know qcc, but it seems to me that you might

Thanks Bart and Peter for your help and the example is working for c chart as

I suspect that you may have set qcc.options(cex) to

ok. I will give the example for which i m getting this error. The data for
plotting R chart and S chart is very huge. SO i will take example for
to start a new R session, don't set your margins for new plots, and try

Please add an reproducible example, so that we can see where it goes wrong.
Maybe the error is raised by faulted data?
