Description

These data consist of measurements of vapour pressure and of the difference between leaf and air temperature.

Usage

leaftemp

Format

This data frame contains the following columns:

CO2level
Carbon Dioxide level low, medium, high
vapPress
Vapour pressure
tempDiff
Difference between leaf and air temperature
BtempDiff
a numeric vector

Examples

print("Fitting Multiple Lines - Example 7.3")

leaf.lm1 <- lm(tempDiff ~ 1 , data = leaftemp)
leaf.lm2 <- lm(tempDiff ~ vapPress, data = leaftemp)
leaf.lm3 <- lm(tempDiff ~ CO2level + vapPress, data = leaftemp)
leaf.lm4 <- lm(tempDiff ~ CO2level + vapPress + vapPress:CO2level,
  data = leaftemp)

anova(leaf.lm1, leaf.lm2, leaf.lm3, leaf.lm4)
