Trebuchet: Trebuchet data

In fastR2: Foundations and Applications of Statistics Using R (2nd Edition)

Trebuchet data

Description

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

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.

Details

Trebuchet1 and Trebuchet2 are subsets of Trebuchet restricted to a single value of counterWt

Source

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

Examples

data(Trebuchet); data(Trebuchet1); data(Trebuchet2)
gf_point(distance ~ projectileWt, data = Trebuchet1)
gf_point(distance ~ projectileWt, data = Trebuchet2)
gf_point(distance ~ projectileWt, color = ~ factor(counterWt), data = Trebuchet) %>%
  gf_smooth(alpha = 0.2, fill = ~factor(counterWt))
