vegdata (version 0.3.2)

syntab: Frequency table

Description

Make relative or absolute frequency tables.

Usage

syntab(veg, clust, type = c('rel','abs','mean.cover'), fullnames=FALSE, limit=0, mupa=NULL, alpha=0.05, minstat=0, dec=0, ...)

Arguments

veg

Vegetation dataframe

clust

Vector with cluster information with length equal to number of rows of veg

type

Relative or absolute frequency, mean species response values or strength of association (see function multipatt in package indicspecis).

fullnames

Replace rownames (LETTERCODES) with full scientific names.

limit

Minimum value to display.

dec

Number of decimals in result.

mupa

Either logical for (not) using multipatt from package indispecies to detect significance of cluster association strength or supply output from previous use of multipatt.

alpha

Significance threshold.

minstat

Minimal indicator value

additional arguments

Examples

data(elbaue)

clust <- vector('integer', nrow(elbaue.env))
clust[elbaue.env$MGL < -50 & elbaue.env$SDGL < 50] <- 1
clust[elbaue.env$MGL < -50 & elbaue.env$SDGL >= 50] <- 2
clust[elbaue.env$MGL >= -50 & elbaue.env$SDGL >= 50] <- 3
clust[elbaue.env$MGL >= -50 & elbaue.env$SDGL < 50] <- 4
# syntab(elbaue, clust, limit=30)

levels(clust) <- c('dry.ld','dry.hd', 'wet.hd','wet.ld')

syntab(elbaue, clust, limit=30, mupa=TRUE)
