Boxplots for cDNA microarray spot statistics
The function maBoxplot produces boxplots of microarray spot
statistics for the classes marrayRaw and
marrayNorm.We encourage users to use "boxplot" rather than "maBoxplot". The name of the arguments have changed.
maBoxplot(m, x="maPrintTip", y="maM", ...)
m |
Microarray object of class |
x |
Name of accessor method for the spot statistic used to stratify the data, typically a slot name for the microarray layout object (see |
y |
Name of accessor method for the spot statistic of interest, typically a slot name for the microarray object |
... |
Optional graphical parameters, see |
If there are more than one array in the batch, the function produces a boxplot for each array in the batch. Such plots are useful when assessing the need for between array normalization, for example, to deal with scale differences among different arrays. Default graphical parameters are chosen for convenience using the function maDefaultPar (e.g. color palette, axis labels, plot title) but the user has the option to overwrite these parameters at any point.
