leaflife

This dataset contains the leaf longevity and leaf mass per area of 75 plant species from four sites in south-eastern Australia. Sites represent contrasts along rainfall and soil phosphorous gradients.

datasets

This package provides methods of fitting bivariate lines in allometry using the major axis (MA) or standardised major axis (SMA), and for making inferences about such lines. The available methods of inference include confidence intervals and one-sample tests for slope and elevation, testing for a common slope or elevation amongst several allometric lines, constructing a confidence interval for a common slope or elevation, and testing for no shift along a common axis, amongst several samples.
