EuroVegChecklist (EVC) and Diagnostic Species for Classes.

Description

This set of functions provides means to analyze diagnostic species of classes of the plant communities dominated by vascular plants (EVC1) as provided with Mucina et al. (2016) in Electronic Appendix S1 (EuroSpeciesList 1).

Usage

evcLookup()
evcCode(obj)
evcClass(obj, plot)
evcMatrix(obj, select, restrict, weighted = TRUE)
evc2vegsoup(obj, restrict, select)

Arguments

obj	A Vegsoup* object.
plot	character. A row name identifying a particular sample in a Vegsoup* object.
select	character. A vector of EVC class codes to be selected for output.
restrict	character. A vector of EVC class codes to restrict the analysis.
weighted	A logical object.

Details

Given an object where species (taxa) are mapped to vegetation classes in the taxonomy in a single column named "evc.class.code" ...

evcCode returns a list with class assignments. evcClass expands the "evc.class.code" string and casts a species by class matrix for a given plot. evcMatrix returns a matrix as in evcClass for the whole object. evcLookup() returns a look table of class codes as used in Mucina et al. (2016). evc2vegsoup aggregates species according to their class membership and uses these as instaed of the original species.
