plotComb2Samples: Plots the correlation in gene expression between two samples

Description

Plots the correlation in gene expression between two samples. Each dot represents a gene, and the dots have a density-dependent coloring. Genes with exceptional behavior can be highlighted by showing their gene symbol.

Usage

plotComb2Samples(object, x, y, trsholdX = NULL, trsholdY = NULL, probe2gene = TRUE, ...)

Arguments

object

ExpressionSet object for the experiment

x

String containing the name of the first sample. This should be a the name of a column in the exprs data of the expressionSet object.

y

String containing the name of the second sample. See x

trsholdX

Vector of two values specifying the X-axis thresholds within which genes should be highlighted by their gene symbol.

trsholdY

Vector of two values specifying the Y-axis thresholds within which genes should be highlighted by their gene symbol.

probe2gene

Boolean indicating whether the probeset should be translated to a gene symbol (used for the default title of the plot)

...

Possibility to add extra plot options. See par
