qicharts: Quality Improvement Charts
Functions for making run charts
[Anhoej, Olesen (2014) <doi:10.1371/journal.pone.0113825>] and basic
Shewhart control charts [Mohammed, Worthington, Woodall (2008)
<doi:10.1136/qshc.2004.012047>] for measure and count data.
The main function, qic(), creates run and control charts and has a
simple interface with a rich set of options to control data analysis
and plotting, including options for automatic data aggregation by
subgroups, easy analysis of before-and-after data, exclusion of one
or more data points from analysis, and splitting charts into
sequential time periods.
Missing values and empty subgroups are handled gracefully.
