Arguments
x |
Object of class "Principal.Coordinates" |
A1 |
First dimenssion of the plot |
A2 |
Second dimenssion of the plot |
LabelRows |
Controls if the points are labelled. Usually TRUE. |
WhatRows |
What Rows to plot. A vector of 0/1 elements. If NULL all rows are plotted |
RowCex |
Size of the points. Can be a single number or a vector. |
RowPch |
Symbols for the points. |
Title |
Title for the graph |
RowLabels |
Labels for the rows. If NULL row names of the data matrix are used. |
RowColors |
Colors for the rows. If NULL row deafault colors are assigned. Can be a single value or avector of colors. |
ColColors |
Colors for the columns (Variables) |
ColLabels |
Labels for the columns (Variables) |
SizeQualInd |
Controls if the size of points depends on the quality of representation. |
SmartLabels |
Controls the way labels are plotted on the graph. If TRUE labels for points with positive x values are placed to the right of the point and labels for points with negative values to the left |
ColorQualInd |
Controls if the color of the points depends on the quality of representation. |
ColorQual |
Darker color for the quality scale. |
PlotSup |
Controls if the supplementary points are plotted. |
Bootstrap |
Controls if the bootstrap points are plotted. |
BootstrapPlot |
Type of plot of the Bootstrap Information. The types are "Ellipse", "CovexHull" or "Star". |
margin |
Margin for the graph. |
PlotClus |
Should the clusters be plotted? |
TypeClus |
Type of plot for the clusters. ("ch"- Convex Hull, "el"- Ellipse or "st"- Star) |
ClustConf |
Percent of points included in the cluster. only the ClusConf percent of the points nearest to the center will be used to calculate the cluster |
CexClustCenters |
Size of the cluster centers |
LegendClust |
Legends for the clusters |
ClustCenters |
Should the cluster centers be plotted |
UseClusterColors |
Should the cluster colors be used in the plot |
ShowAxis |
Logical variable to control if the coordinate axes should appear in the plot. The default value is FALSE because for most of the biplots its presence is irrelevant. |
PlotBinaryMeans |
Plot the mean of the presence points for each variable |
MinIncidence |
Minimum incidence to keep a variable |
ShowBox |
Should a box around the poitns be plotted? |
ColorSupContVars |
Colors for the supplementary continuous variables |
ColorSupBinVars |
Colors for the supplementary binary variables |
ColorSupOrdVars |
Colors for the supplementary ordinal variables |
TypeScale |
Type of scales for the plot |
SupMode |
Mode of the supplementary variables |
PlotSupVars |
Should the supplementary variables be plotted |
... |
Additional parameters for graphical representations |
Details
Graphical representation of an Principal coordinates Analysis controlling visual aspects of the plot as colors, symbols or sizes of the points.
