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)
