Package: qicharts2 Title: Quality Improvement Charts Version: 0.8.1 Authors@R: person('Jacob', 'Anhoej', email = 'jacob@anhoej.net', role = c('aut', 'cre')) Description: Functions for making run charts, Shewhart control charts and Pareto charts for continuous quality improvement. Included control charts are: I, MR, Xbar, S, T, C, U, U', P, P', and G charts. Non-random variation in the form of minor to moderate persistent shifts in data over time is identified by the Anhoej rules for unusually long runs and unusually few crossing [Anhoej, Olesen (2014) ]. Non-random variation in the form of larger, possibly transient, shifts is identified by Shewhart's 3-sigma rule [Mohammed, Worthington, Woodall (2008) ].
