xmp10.08 {Devore6} | 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`
