In flower: Tools for characterizing flowering traits

Description

Relative to the formula of Mahoro (2002),we suggested the reference object (b) calculated in a polulation was better than in a individua. It measures the rank order of flowering for individual plants within a population.

Usage

RIpop(dd, pop, ind)

Arguments

dd	Flowering data.
pop	Group of Population.
ind	ID of individual.

Details

ri=sum(aij/bi);(j=1:p)

Value

i	individuals
j	time during the flowering from beginning to pike of flowering p
r	the rank of each individual
aij	flowers that had already open in the individual by the jth census day
bi	the total number of flowers opening in the individual during the season
xij	xij=aij/bi
