plot.estPI: Plot an estPI Object

In gMWT: Generalized Mann-Whitney Type Tests

Plot an estPI Object

Description

Plots an estPI object.

Usage

 ## S3 method for class 'estPI'
plot(x,col="black",highlight,hlCol="red",pch=20,zoom=FALSE,...)

Arguments

x	Object of class estPI.
col	Vector of colors of the scatterplot.
highlight	Vector with positions, which shall be marked in special color.
hlCol	Color of highlighted spots.
pch	Dot type of the plot.
zoom	Logical, shall the plots be zoomed to interesting areas?
...	Additional parameters.

Details

This function plots the probabilistic indices from an estPI object. Additional graphical parameters are col, that specifies the colors of the points used in the plot. Furthermore there is the option to highlight the probabilistic indices for specified variables. Those are defined with the highlight option and the hlCol color. One possible application of this is to highlight only the significant test results, or e.g. in the genetic context only those genes, which are located on a certain chromosome.

The boolean option zoom is meant for plotting the graph in a different scale and it adjusts the limits of the x and y axes to the minimum and maximum of the corresponding probabilistic index.

Value

A plot for estPI object

Examples

  X <- c(sample(15))
  g <- c(1,1,1,2,2,2,2,3,3,3,4,4,4,4,4)
  res <- estPI(X,g,type="single")
  plot(res)

  X <- matrix(c(rnorm(5000,1.5,2),rnorm(6000,2,2),rnorm(4000,3.5,1),rnorm(3000,2.5,1)),
           byrow=TRUE, ncol=100)
  colnames(X) <- letters[1:100]
  g <- c(rep(1,50),rep(2,60),rep(3,40),rep(4,30))

  res <- estPI(X,g,type="single")
  plot(res)
