Usage

modelcars

Format

This data frame contains the following columns:

distance.traveled

a numeric vector consisting of the lengths traveled (in cm)

starting.point

a numeric vector consisting of the distance of the starting point from the top of the ramp (in cm)

Examples

plot(modelcars)
modelcars.lm <- lm(distance.traveled ~ starting.point, data=modelcars)
aov(modelcars.lm)
pause()

print("Response Curves - Example 4.6")
attach(modelcars)
stripchart(distance.traveled ~ starting.point, vertical=TRUE, pch=15,
           xlab = "Distance up ramp", ylab="Distance traveled")
detach(modelcars)
