Description

Creates foreground-background plots.

Usage

## S3 method for class 'RGList'
plotFB(x, array=1, lim="separate", pch=16, cex=0.2, ...)
## S3 method for class 'EListRaw'
plotFB(x, array=1, pch=16, cex=0.2, ...)

Arguments

`x`	an `RGList` or `EListRaw` object.
`array`	integer giving the array to be plotted.
`lim`	character string indicating whether the red and green plots should have `"separate"` or `"common"` x- and y- co-ordinate limits.
`pch`	vector or list of plotting characters. Defaults to integer code 16.
`cex`	numeric vector of plot symbol expansions.

Details

A foreground-background plot is a plot of log2-foreground vs log2-background for a particular array. For two-color arrays, this function produces a pair of plots, one for the green channel and one for the red.

See points for possible values for pch, col and cex.
