dendro: Hierarchical Cluster (Dendrogram)

In SvenRubanschi/simpECO: Simple ecology

Description

Creates a hierachical dendrogram. It is also possible to colour the leaves by group.

Usage

dendro(veg, method = "bray", env = NULL, group.col = NULL,
  colvec = "black", pch = 20, cex = 1, lab.cex = 0.7)

Arguments

veg	vegetation matrix
method	method of the dissimilarity index
env	environment matrix with the group information
group.col	column in which the group is located
colvec	colour vector of the groups; like c("col1","col2","col3") or c(1,2,3)
pch	point vector of the groups; like c(1,2,3)
cex	scales plot
lab.cex	scales of label

Note

Information about the different dissimilarity indexes read vegdist

Examples

library(vegan)
data(dune)
data(dune.env)

# Simple dendrogram
den <- dendro(veg = dune)
plot(den, horiz = TRUE)

# Dendrogram coloured by group
Cvec = c("black", "gray20", "gray40", "gray80")
Pch = c(15, 16, 17, 18)

den <- dendro(veg = dune, env = dune.env, group.col = 3, colvec = Cvec, pch = Pch, cex = 2)
plot(den, leaflab = "none", horiz = TRUE)
