ch.plot: Cross-hair plotting functions for 2D NMDS plots.

In ECGen/ComGenR: Functions for COMmunity GENetics analyses in R

Description

This is a high level plotting function that produces a "cross-hair" plot of centroids and standard deviations for groups of ordinated points, as is often desired with community genetics data.

Usage

ch.plot(
  x = "ordination matrix",
  g = "groupings",
  cex = 1,
  lwd = 1,
  mu.pch = 19,
  pt.col = 1,
  bar.col = 1,
  xlab = "X1",
  ylab = "X2"
)

Arguments

x	Ordination matrix.
g	Grouping (i.e. genotype) vector.
cex	Value to scale centroids.
lwd	Line width scaler.
mu.pch	Centroid shape.
pt.col	Centroid color.
xlab	X-axis label: DEFAULT = X1.
ylab	Y-axis label: DEFAULT = X2.
car.col	Error bar color.

Details

Simple way to plot centroids of groups of ordinated points with standard error values.

Value

Produces a 2-D plot of centroids with variance bars (i.e. "cross-hairs").
