compute_growth: Compute growth of trees

In forestecology: Fitting and Assessing Neighborhood Models of the Effect of Interspecific Competition on the Growth of Trees

Description

Based on two tree censuses, compute the average annual growth in dbh for all trees.

Usage

compute_growth(census_1, census_2, id)

Arguments

census_1	A data frame of the first census.
census_2	A data frame of the second (later) census
id	Name of variable that uniquely identifies each tree common to census_1 and census_2 allowing you to join/merge both data frames.

Value

An sf data frame with column growth giving the average annual growth in dbh.

growth_ex <-
  compute_growth(
    census_1 = census_1_ex %>%
      mutate(sp = to_any_case(sp) %>% factor()),
    census_2 = census_2_ex %>%
      filter(!str_detect(codes, "R")) %>%
      mutate(sp = to_any_case(sp) %>% factor()),
    id = "ID"
