Arguments

x

Object qcs (Quality Control Statical)

title

an overall title for the plot

subtitle

a sub title for the plot

xlab

a title for the x axis

ylab

a title for the y axis

ylim

the y limits of the plot

center.nominal

a value specifying the center of group statistics or the "target" value of the process

limits.specification

a two-value vector specifying control limits.

limits.alert

a two-value vector specifying control alert limits.

type.data

a string specifying the type of data.

...

arguments to be passed to or from methods.

conf.nsigma.alert

a numeric value used to compute control limits, specifying the number of standard deviations (if conf.nsigma > 1) or the confidence level (if 0 < conf.nsigma < 1).

conf.nsigma

a numeric value used to compute control limits, specifying the number of standard deviations (if conf.nsigma > 1) or the confidence level (if 0 < conf.nsigma < 1).
