Metal Plates Thickness

Description

This data set contains the thickness and additional data for 24 metal plates.

Usage

data("ss.data.thickness")

Format

A data frame with 24 observations on the following 5 variables.

thickness

a numeric vector with the thickness (in)

day

a factor with the day (two days)

shift

a factor with the shift (two shifts)

dayshift

a factor with the day-shift combination

position

a factor with the position of the thickness with respect to the nominal value of 0.75 in

Details

This data set illustrates concepts in the book “Quality Control with R”. Note that, in the book, the data set is named plates and it is created sequentially throughout the examples.
