Two simulated censuses for testing demography code

Builds a pair of ForestGEO-style tree tables five years apart, with simulated mortality, recruitment and growth, for testing tidydiversity::stems_demography(). Not real census data.

Usage

geo_example_censuses(n = 80, seed = 1, time = 5)

Arguments

n

Number of trees in census 1.

seed

RNG seed.

time

Interval in years between censuses.

Value

A list with census1 and census2 tibbles.

Examples

cens <- geo_example_censuses()
tidydiversity::stems_demography(cens$census1, cens$census2, time = 5, dbh_unit = "mm")
