| GO2heatmap {annotate} | R Documentation |
For a given GO category or KEGG pathway, all probes in the supplied data are mapped to the pathway and a heatmap is produced.
GO2heatmap(x, eset, data, ...) KEGG2heatmap(x, eset, data, ...)
x |
The name of the category or pathway. |
eset |
An exprSet providing the data. |
data |
The name of the chip. |
... |
Additional parameters to pass to heatmap. |
For the given pathway or GO category all matching probes are
determined, these are used to subset the data and heatmap is
invoked on that set of data. Extra parameters can be passed through to
heatmap using the ... parameter.
The annotation slot of the eset argument is used to
determine the appropriate annotation data to use.
The value returned by heatmap is passed back to the user.
