run.length or more
consecutive points lie on one side of center line of a Shewhart control
chart.
runs.target(object, run.length=5)
"shewhart". Usually the return object of a call to the
shewhart function.
run.length or more points are consecutively
on one side of the center line of the control chart.
shewhart,
runs.target is applied (by default) to the
Shewhart control chart and all the violating points are highlighted.
runs.target and
beyond.limits are the two rules applied to a Shewhart
control chart by default. Any violating points are highlighted. Both
runs.target
and
beyond.limits are called by
shewhart.rules which
is called by
shewhart.
runs.target
may be applied directly to an object inheriting from class
"shewhart"
to obtain the indices of points violating the runs rule.
qc.chart <- shewhart(qcc(matrix(rnorm(100),ncol = 5), "xbar")) runs.target(qc.chart)
