This function returns a list for each control chart and returns the id of all observations that are out of control in that control chart.
which_ooc(cclist)A list of as many data.frame objects as
the control charts in cclist.
Each data frame has two columns, the n contains
an index number giving the observation in the
phase II data set, i.e. 1 for the first observation,
2 for the second, and so on,
while the id column contains the id of the observation,
which can be general and
depends on the specific data set.
A data.frame produced by
control_charts_sof_pc.
