ranova {petitr}

Analysis of Variance on per capita growth rate pseudovalues

Description

Accepts as input a series (list) of individual life tables (see r,petitr,life1), calculates the Jackknife estimator of r (per capita growth rate) on each table, and achieves a one way analysis of variance on the set of pseudovalues corresponding to each table.

Usage

ranova(listab, levels = NULL)

Arguments

listab

list of life tables. must be of class list, and each table of class data.frame

levels

a character vector giving level names for each life table. If NULL, the levels are named l1,l2, etc..

Value

a data frame with two columns: the set of pseudovalues, and a factor named pop. Can be retrieved and used for more sophisticated factor organisation
