Statistical Process Control <strong>and</strong> R:<br />
A cautious beg<strong>in</strong>n<strong>in</strong>g<br />

A lot of monographs were written about the area of statistics called Statistical Process<br />
Control. Moreover, <strong>in</strong> nearly all commercial statistical packages some SPC rout<strong>in</strong>es are<br />
<strong>in</strong>cluded. Up to now, it is not possible to call a R function for comput<strong>in</strong>g, e. g., the<br />
Average Run Length (ARL) of an EWMA control chart. Additionally, R provides a f<strong>in</strong>e<br />
framework for timely <strong>in</strong>corporat<strong>in</strong>g new results of comput<strong>in</strong>g SPC relevant quantities.<br />
Thus, it is time for design<strong>in</strong>g a SPC package for R. The talk will give an impression<br />
of a very early state of a SPC package, which allows to compute the (zero-state) ARL<br />
<strong>and</strong> steady-state ARL of EWMA <strong>and</strong> CUSUM control charts. Naturally, the ideas <strong>and</strong><br />
solutions have to be discussed more <strong>in</strong>tensively than for mature R packages <strong>and</strong> each<br />
SPC <strong>and</strong>/or R user/developer is <strong>in</strong>vited to debate the whole th<strong>in</strong>g.
