MultiTraits (version 0.5.0)

CSR: Calculate CSR strategy for multiple plant species

Description

This function processes a dataframe containing leaf traits (LA, LDMC, SLA) and applies the Strate_CSR function to each row.

Usage

CSR(data)

Value

A dataframe with the original input data and additional columns:

• C: Competitive strategy score

• S: Stress-tolerant strategy score

• R: Ruderal strategy score

• type: The dominant CSR strategy type

Arguments

data

A dataframe containing columns for LA (Leaf Area), LDMC (Leaf Dry Matter Content), and SLA (Specific Leaf Area).
