LHS: Calculate LHS (Leaf-Height-Seed) Strategy

In MultiTraits: Analyzing and Visualizing Multidimensional Plant Traits

Calculate LHS (Leaf-Height-Seed) Strategy

Description

This function calculates the LHS strategy for plant species based on their SLA (Specific Leaf Area), Height, and Seed Mass values.

Usage

LHS(data)

Arguments

data	A data frame containing columns for SLA, Height, and SeedMass.

Details

The function calculates median values for SLA, Height, and SeedMass from the input data. It then determines the LHS strategy for each species based on whether its trait values are less than or equal to (S) or greater than (L) the median values.

The resulting strategy is a combination of three letters (S or L) representing Leaf (SLA), Height, and Seed (SeedMass) respectively, separated by hyphens.

Value

A data frame with an additional column 'LHS_strategy' containing the calculated LHS strategy.
