Description

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

Usage

data(leaftemp)

source

Katharina Siebke and Susan von Cammerer, Australian National University.

Examples

data(leaftemp)
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)

summary(leaf.lm2)
plot(leaf.lm2)
