leaftemp: Leaf and Air Temperature Data

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

# NOT RUN {
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)
