In katenambiar/pmpa: Peptide Microarray Pre-Processing and Analysis

Description

Creates image plot representing the microarray foreground or background signal intensity organised by the spatial location of the spots on the array.

Usage

plotImage(x, ...)

## S4 method for signature 'MultiSet'
plotImage(x, arr = 1, slot = "bg", lowcol, highcol,
  ncols = 123, titletext, transform = "none", ...)

Arguments

x	MultiSet object with fMedian and/or bMedian matrices in the assayData slot and layout data (block, column and row) in the fData slot.
lowcol	Colour associated with low signal intensities
highcol	Colour associated with high signal intensities
ncols	number of colour shades used

Value

MultiSet object with transformed and background corrected foreground signal in the fMedian matrix
