Add composite ID columns to data

Creates a tree_ID and/or a plot_ID column that contain unique tree and plot identifiers, respectively. These are created by pasting together the values for UNITCD, STATECD, COUNTYCD, PLOT and in the case of trees SUBP and TREE.

Usage

fia_add_composite_ids(data)

Arguments

data

A tibble or data frame with at least the UNITCD, STATECD, COUNTYCD and PLOT columns

Value

The input tibble with a plot_ID and possibly also a tree_ID column added

Examples

db <- fia_load("RI", dir = system.file("exdata", package = "forestTIME"))
fia_add_composite_ids(db$TREE)
