ss.rr.plots: Gage R & R plots

In industRial: Data, Functions and Support Materials from the Book "industRial Data Science"

Description

Extracts stand alone plots from the ss.rr function of the SixSigma package.

Usage

ss.rr.plots(
  var,
  part,
  appr,
  lsl = NA,
  usl = NA,
  sigma = 6,
  data,
  main = "Six Sigma Gage R&R Study",
  sub = "",
  alphaLim = 0.05,
  errorTerm = "interaction",
  digits = 4
)

Arguments

var	Measured variable
part	Factor for parts
appr	Factor for appraisers (operators, machines, ...)
lsl	Numeric value of lower specification limit used with USL to calculate Study Variation as %Tolerance
usl	Numeric value of upper specification limit used with LSL to calculate Study Variation as %Tolerance
sigma	Numeric value for number of std deviations to use in calculating Study Variation
data	Data frame containing the variables
main	Main title for the graphic output
sub	Subtitle for the graphic output (recommended the name of the project)
alphaLim	Limit to take into account interaction
errorTerm	Which term of the model should be used as error term (for the model with interation)
digits	Number of decimal digits for output

Details

This is a modified version of the function ss.rr from the SixSigma package that allows to extract the individual plots from the output report. The input arguments of the function are the same as the original function. See the original function help with ?ss.rr for full documentation.

Value

Generates a list output that can be assigned to a user created variable. The plots can then be accessed with the syntax variable$plot1 to plot6.
