view.order {pga}R Documentation

Create an Order Plot

Description

Visualizes the result from pga; it's always used together with view.bubble. The order plot is very similar to the so-called scree plot from principal component analysis. To select variables, we look for a big gap in this plot and select the top few variables. The bubble plot (see view.bubble) will tell us which variables are actually on the top.

Usage

view.order(obj, grid = F,  filename=NULL, ...)

Arguments

obj object created by pga.
grid if TRUE, horizontal grid lines are added.
filename name to store the output file. If NULL (default), the plot will be made to the standard R graphic device.
... other graphic parameters, such as ylim=c(0,1).

Note

Please see pga-package for an introductory overview and examples.
