focal_vs_comp_ex: Example focal versus comp data frame

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

Description

This is an example focal versus comp data frame. The rows are focal trees which are repeated for all competitor trees within a specified distance from them. In this case that distance is 1. This is the focal versus comp for growth_spatial_ex.

Usage

focal_vs_comp_ex

Format

A tibble::tbl_df:

focal_ID

Tree identification number for the focal tree

focal_sp

Species of the focal tree

dbh

Diameter at breast height of the focal tree at the first census

foldID

The CV-fold that the focal tree is in

geometry

The point location of the focal tree

growth

The average annual growth of the focal tree between censuses

comp

A list-column: characteristics of the relevant competitor trees

The comp list-column contains tibble::tbl_dfs with columns:

comp_ID

Tree identification number for the competitor tree

dist

The distance between the focal and comp tree, this will be less than the max distance specified.

comp_sp

Species of the comp tree

comp_x_var

Numerical variable associated with comp tree
