epGraphs: epGraphs: ExPosition plotting function

In ExPosition: Exploratory Analysis with the Singular Value Decomposition

Description

ExPosition plotting function which is an interface to prettyGraphs.

Usage

epGraphs(res, x_axis = 1, y_axis = 2, epPlotInfo = NULL, DESIGN=NULL, 
	fi.col = NULL, fi.pch = NULL, fj.col = NULL, fj.pch = NULL, col.offset = NULL, 
	constraints = NULL, xlab = NULL, ylab = NULL, main = NULL, 
	contributionPlots = TRUE, correlationPlotter = TRUE,
	graphs = TRUE)

Arguments

res	results from ExPosition
x_axis	which component should be on the x axis?
y_axis	which component should be on the y axis?
epPlotInfo	A list ($Plotting.Data) from epGraphs or ExPosition.
DESIGN	A design matrix to apply colors (by pallete selection) to row items
fi.col	A matrix of colors for the row items. If NULL, colors will be selected.
fi.pch	A matrix of pch values for the row items. If NULL, pch values are all 21.
fj.col	A matrix of colors for the column items. If NULL, colors will be selected.
fj.pch	A matrix of pch values for the column items. If NULL, pch values are all 21.
col.offset	A numeric offset value. Is passed to createColorVectorsByDesign.
constraints	Plot constraints as returned from prettyPlot. If NULL, constraints are selected.
xlab	x axis label
ylab	y axis label
main	main label for the graph window
contributionPlots	a boolean. If TRUE (default), contribution bar plots will be created.
correlationPlotter	a boolean. If TRUE (default), a correlation circle plot will be created. Applies to PCA family of methods (CA is excluded for now).
graphs	a boolean. If TRUE, graphs are created. If FALSE, only data associated to plotting (e.g., constraints, colors) are returned.

Details

epGraphs is an interface between ExPosition and prettyGraphs.

Value

The following items are bundled inside of $Plotting.Data:

$fi.col	the colors that are associated to the row items ($fi).
$fi.pch	the pch values associated to the row items ($fi).
$fj.col	the colors that are associated to the column items ($fj).
$fj.pch	the pch values associated to the column items ($fj).
$constraints	axis constraints for the plots (determines end points of the plots).

Examples

	#this is for ExPosition's iris data
	data(ep.iris)
	pca.iris.res <- epPCA(ep.iris$data)
	#this will put plotting data into a new variable.
	epGraphs.2.and.3 <- epGraphs(pca.iris.res,x_axis=2,y_axis=3)
