Analysis of community ecology data in R

Theory R functions Examples

Interpreting results of numerical classification:

• project results onto ordination diagram
• compare groups using selected criteria (e.g. environmental variables)
• evaluate the quality of the classification (e.g. the numbers of misclassified plots using the silhouette diagram)
• compare groups based on their species composition – identify species which have the highest fidelity to given cluster (characteristic, diagnostic or indicator species)
