fgbg.visu: Visualisation of foreground and background fluorescence spot...

In OLIN: Optimized local intensity-dependent normalisation of two-color microarrays

Description

This function generates 2D-plots of the foreground, background and background corrected fluorescence intensities of channel 1 and of channel 2, respectively.

Usage

fgbg.visu(obj,label)

Arguments

obj	object of class “marrayRaw”
label	character string for labelling. It will be added to the title of the first sub-plot.

Details

The function fgbg.visu produces 2D-representations of the foreground and background intensities for both fluorescence channels (as stored in obj). Additionally, a plot of the difference between fore- and background intensities is generated (background-corrected intensities). All intensities are log2-transformed. The colour range for plotting is defined by 0 and the maximum of the logged intensity for each sub-graph separately.
