Description

Six points in a row steadily increasing or decreasing.

Usage

Rule3(x, nPoints = 6, convention = 1, equalBreaksSeries = 1, ...)

Arguments

x	Numerical vector
nPoints	Sequence of consequtive points to be evaluated
convention	Calculation according to 'minitab' or 'jmp' (see details)
equalBreaksSeries	Equal values break consequtive series of points
...	unspecified arguments of a function

Details

0 means: ok
1 means: violation

parameter equalBreakSeries is internally encoded as: 1 for TRUE and 2 for FALSE

parameter convention is internally encoded as: 1 for 'minitab' and 2 for 'jmp'

Difference in convention parameter is as follows:
'minitab' - seven points in a row steadily increasing or decreasing
'jmp' - six points in a row steadily increasing or decreasing
