plotCombination2genes: Plot a Combination of Two Genes

Description

Plot a Combination of Two Genes

Usage

plotCombination2genes(probesetId1 = NULL, probesetId2 = NULL, geneSymbol1 = NULL,
 geneSymbol2 = NULL, object, groups, addLegend = TRUE, legendPos = "topleft", probe2gene = TRUE, colvec = NULL, ...)

Arguments

probesetId1
First probeset id, plotted in the x-axis
probesetId2
Second probeset id, plotted in the y-axis
geneSymbol1
First gene symbol, plotted in the x-axis
geneSymbol2
Second gene symbol, plotted in the y-axis
object
ExpressionSet object for the experiment
groups
string containing the name of the grouping variable
addLegend
Logical value to indicate whether a legend needs to be drawn.
legendPos
Position on the graph where to put the legend
probe2gene
should the probeset be translated to a gene symbol (used for the default title of the plot)
colvec
a character vector of colors. If not specified it will be automatically generated by a4palette
...
This allows to specify typical arguments in the plot function

Value

  • If a gene id is given, the plots for only the first probeset is displayed and a character vector of corresponding probeset IDs is returned invisibly. It is a list containing
  • probeset1Probeset ids measuring 'gene1'
  • probeset1Probeset ids measuring 'gene1'
  • If a probeset id is given, one single profile plot for the probeset is displayed.
