fitness.landscape       A function to estimate fitness landscapes, i.e.
                        the relationship between popualtion mean
                        fitness and population mean phenotype.
gam.gradients           A function to calculate selection gradients
                        from generalized additive model-based
                        characterizions of fitness functions.

gppr.gradients          A function to calculate selection gradients
                        from generalized additive model-based
                        characterizions of fitness functions.

                        neonatal survival
moments.differentials   Calculates selection differentials directly
                        from the differences in phenotypic moments
                        before and after selection.
