linestack: Plots One-dimensional Diagrams without Overwriting Labels

Description

Function linestack plots vertical one-dimensional plots for numeric vectors. The plots are always labelled, but the labels are moved vertically to avoid overwriting.

Usage

linestack(x, labels, cex = 0.8, side = "right", hoff = 2, air = 1.1,
    at = 0, add = FALSE, axis = FALSE, ...)

Arguments

x
Numeric vector to be plotted.
labels
Text labels used instead of default (names of x).
cex
Size of the labels.
side
Put labels to the "right" or "left" of the axis.
hoff
Distance from the vertical axis to the label in units of the width of letter m.
air
Multiplier to string height to leave empty space between labels.
at
Position of plot in horizontal axis.
add
Add to an existing plot.
axis
Add axis to the plot.
...
Other graphical parameters to labels.

Value

  • The function returns invisibly the shifted positions of labels in user coordinates.

Examples

Run this code
## First DCA axis
data(dune)
ord <- decorana(dune)
linestack(scores(ord, choices=1, display="sp"))
linestack(scores(ord, choices=1, display="si"), side="left", add=TRUE)
title(main="DCA axis 1")
