Rule6 {Rspc}

Rule 6

Description

Four or five out of five points in a row are more than 1 standard deviation from the mean in the same direction.

Usage

Rule6(x, zoneB, minNPoints = 4, nPoints = 5, ...)

Arguments

x

Numerical vector

zoneB

Vector of zone borders

minNPoints

Minimal number of points in a sequence violating a rule

nPoints

Sequence of consequtive points to be evaluated

...

unspecified arguments of a function

Details

0 means: ok
1 means: violation

inequality used during evaluation Rule is violated also if the first four points are beyond the 1 standard deviation from the mean During calculation of EvaluateRules function wiht controlLimitDistance <= 1, the evaluation of this rule is suppressed

Value

Vector of the same length as x

Examples

limits = CalculateLimits(x = rnorm(10), lcl = NA, cl = 100, ucl = NA, type = 'i')
zones = CalculateZoneBorders(limits)
Rule6(x = rnorm(20), zoneB = zones, minNPoints = 4, nPoints = 5)
#zones is object created by function CalculateZoneBorders()
