In emilopezcano/SixSigma: Six Sigma Tools for Quality Control and Improvement

Get out-of-control profiles

Description

Returns a list with information about the out-of-control profiles given a set of profiles and some control limits

Usage

outProfiles(profiles, x = 1:nrow(profiles), cLimits, tol = 0.5)

Arguments

profiles	Matrix of profiles
x	Vector with the independent variable
cLimits	Matrix with the prototype and confidence bands profiles
tol	Tolerance (%)

Value

a list with the following elements:

labOut	labels of the out-of-control profiles
idOut	ids of the out-of-control profiles
pOut	proportion of times the profile values are out of the limits

    cLimits = wb.limits,
    outControl = wb.out.phase2$idOut,
