Makes an MA plot, given two vectors of expression values

Description

Makes an MA plot, given two vectors of expression values. Similar to plotMA (See plotMA) from the affy package, except that this method requires no special affy objects and works on plain vanilla data.

Usage

maplot(p1, p2)

Arguments

p1 numeric. Vector of 1st sample's expression values.
p1 numeric. Vector of 2ns sample's expression values.

Details

A LOESS spline is drawn through the point cloud as additional measure of centrality.
