recluster (version 2.8)

recluster.plot.sites.col: Plotting RGB dots on a custom coordinate space

Description

This function plots the RGB dots belonging to a matrix obtained by recluster.col on a user defined set of coordinates (usually longitude and latitude) for original sites.

Usage

recluster.plot.sites.col (long, lat, mat, cext = 0.3, cex = 1, cex.axis = 0.7, 
cex.lab = 0.8, text = FALSE, pch=21, add = FALSE,...)

Arguments

long

A vector indicating longitude for cases.

lat

A vector indicating latitude for cases.

mat

A matrix inherited by recluster.col.

text

A logical indicating if row names should be plotted.

cext

Dimension for row names.

cex

Dimension of dots.

cex.axis

Dimension of axis labels.

cex.lab

Dimension of labels.

add

A logical. If TRUE then the points are added to an existing graph.

pch

The symbol to use when plotting points
