Unique Plot ID Code

Description

When working with a large data set of multiple stands and plots, it can be helpful to provide each individual plot a unique ID code. As an example, this ensures that when using some functions like basal area of larger trees, you don't confused plot 2 in stands 1, 2, 3.

Usage

Unique.ID(Stand, Plot)

Arguments

Stand	The unique stand ID for each stand.
Plot	The unique plot ID for each plot within a stand.

Details

This is a required function for the BA.Larger.Trees and CCF.Larger functions. This may also be helpful in your own analysis to make sorting easier.

Value

This function returns a vector of length n with unique id numbers for every individual plot.
