fgbg.visu {OLIN} | R Documentation

## Visualisation of foreground and background fluorescence spot intensities in both channels

### 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.
