gx.2dproj.plot: Function to Display a Saved 2-D Projection Object

Description

Displays the 2-d projection saved from gx.2dproj, optionally the row numbers of the input matrix may be displayed instead of the default plotting symbol.

Usage

gx.2dproj.plot(save, idplot = FALSE, main = "", ...)

Arguments

save

the saved object from gx.2dproj.

idplot

to display the input matrix row numbers set idplot = TRUE.

main

an alternative plot title to that in the saved object from gx.2dproj, see Details below.

...

further arguments to be passed to methods concerning the plot. For example, if smaller plotting characters are required, specify cex = 0.8; or if some colour other than black is required for the plotting characters, specify col = 2

Details

If main is undefined the plot title from the saved object from gx.2dproj is displayed. If no plot title is required set main = "", or if a user defined plot title is required it should be defined in main, e.g., main = "Plot Title Text". The x- and y-axis labels are those in the saved object from gx.2dproj and indicate the type of 2-d projection in the display.

Examples

Run this code

## Make test data available
data(sind.mat2open)

## Display default 2-D projection
sind.save <- gx.2dproj(ilr(sind.mat2open))

## Display saved object
gx.2dproj.plot(sind.save,
main = "Howarth & Sinding-Larsen
Stream Sediments, ilr Transformed Data")

## Clean-up
rm(sind.save)
