Obtain a growth transition matrix — get_growth

Obtain a growth transition matrix from a vector of growth increments.

Usage

get_growth_matrix(midpoint, increment)

Arguments

midpoint: a vector of midpoints associated with each increment. These midpoints do not need to be evenly spaced.
increment: a vector of growth increments.

Value

A growth transition matrix matrix.

Examples

mp <- seq(31, 91, 10)
inc <- get_growth_increment(midpoint = mp, gobs = NULL)
get_growth_matrix(midpoint = mp, increment = inc)
