xmp10.08 {Devore5}R Documentation

data from Example 10.8

Description

The xmp10.08 data frame has 22 rows and 2 columns of data on the elastic modulus of Mg-based alloys obtained by a new ultrasonic process for specimens produced using three different casting processes.

Usage

data(xmp10.08)

Format

This data frame contains the following columns:

elastic
a numeric vector of the elastic modulus (GPa)
type
a factor indicating the casting process with levels Die, Permanent, and Plaster
