plot.svb: Plot of Signal vs. Background

In gnyamundanda/sma: Statistical Microarray Analysis

Description

Produces a scatter plot of background corrected signal intensities and background intensities.

Usage

plot.svb(x, channel="R", image.id=1, S.isbgcor=FALSE, ...)

Arguments

x	a numeric list of signal and background intensities, can be raw or background corrected data.
channel	the specific channel to which the intensities to be considered, correspond to, that is, either red or green. The default channel is red.
image.id	integer value; the index of the slide which is considered
S.isbgcor	logical flag, equal to TRUE if the signal intensities in x contain background corrected signal intensities instead of raw signal intensities. By default this is set to FALSE.
...	graphical parameters may also be supplied as arguments to the function (see par).

Value

a plot is created on the current graphics device.

# mouse.data <- init.data() ## see \emph{init.data}

plot.svb(mouse.data, "green", 3) 
## thiscreates a plot of the signal versus background intensities 
## for the green channel, using data collected from the third slide.
