tv.traits: Load species traits from Turboveg reference list

Description

Loading Turboveg ecodbase or any other specified dBase file in this directory and do basic data evaluation. Empty columns are eliminated. meanTraits will calculate mean trait values like mean Ellenberg indicator values (see vignette).

Usage

tv.traits(db, trait.db = 'ecodbase.dbf', refl, quiet = FALSE, ...)
meanTraits(trait, veg, refl, trait.db = 'ecodbase.dbf', join = 'LETTERCODE', 
zero.is.NA = TRUE, ...)

Arguments

db

Path name to the Turboveg database directory

trait.db

Name of species trait DBase file, default is 'ecodbase'

refl

Name of the taxonomic reference list, if veg is not loaded with tv.veg

quiet

Hide messages

trait

Name of the column to use from the trait table

veg

vegetation matrix

join

Column name of the trait table corresponding to the colnames of the vegetation matrix

zero.is.NA

Should zero trait values handled as NA values

...

additional arguments for tv.traits

Value

• data.frame of ecological traits, see metainfo(refl, eco=TRUE).

Details

You can use the final output line to make a summary statistic for attributes with potentially misleading '0' values. Just delete the " at beginning and end.

Examples

veg <- tv.veg('elbaue', cover.transform='pa')
# mEIV <- meanTraits('OEK_F', veg, 'ecodbase.dbf')
site <- tv.site('elbaue')
# plot(site$MGL, mEIV)
