trebuchet: Trebuchet data

In fastR: Data sets and utilities for Foundations and Applications of Statistics by R Pruim

Description

Measurements from an experiment that involved firing projectiles with a small trebuchet under different conditions.

Usage

data(trebuchet)
data(trebuchet1)
data(trebuchet2)

Format

Data frames with the following variables.

object

the object serving as projectilebean big washerb bigWash BWB foose golf MWB SWB tennis ball wood

projectileWt

weight of projectile (in grams)

counterWt

weight of counter weight (in kg)

distance

distance projectile traveled (in cm)

form

a factor with levels a b B c describing the configuration of the trebuchet.

Source

Data collected by Andrew Pruim as part of a Science Olympiad competition.

Examples

data(trebuchet); data(trebuchet1); data(trebuchet2)
xyplot(distance~projectileWt, trebuchet1)
xyplot(distance~projectileWt, trebuchet2)
xyplot(distance~projectileWt, groups=projectileWt, trebuchet)

The 'mosaic' package masks several functions from core packages in order to add 
additional features.  The original behavior of these functions should not be affected by this.

Note: If you use the Matrix package, be sure to load it BEFORE loading mosaic.
