GO2heatmap {annotate} | R Documentation

## Compute a heatmap for the specified data, for either a GO category or a KEGG pathway.

### Description

For a given GO category or KEGG pathway, all probes in the supplied data are mapped to the pathway and a heatmap is produced.

### Usage

    GO2heatmap(x, eset, data, ...)
    KEGG2heatmap(x, eset, data, ...)

### Arguments

`x` | The name of the category or pathway.
`eset` | An `ExpressionSet` providing the data.
`data` | The name of the chip.
`...` | Additional parameters to pass to `heatmap`.

### Details

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.

### Value

The value returned by `heatmap` is passed back to the user.

     }
