plotComb2Samples: Plots the correlation in gene expression between two samples
In a4Base: Automated Affymetrix Array Analysis Base Package

Description Usage Arguments Value Author(s) See Also Examples

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.

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

`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`

No returned value, a plot is drawn to the current device.
