GOmnplot {annotate} | R Documentation

## A function to plot by group means against each other.

### Description

For a two sample comparison, as determined by `group`, and a specified KEGG pathway or GO category, per group means are computed and plotted against each other.

### Usage

    GOmnplot(x, eset, data = "hgu133plus2", group, ...)
    KEGGmnplot(x, eset, data = "hgu133plus2", group, ...)

### Arguments

`x` | The name of the KEGG pathway or GO category.
`eset` | An `ExpressionSet` containing the data.
`data` | The name of the chip that was used to provide the data.
`group` | The variable indicating group membership, should have two different values.
`...` | Extra parameters to pass to the call to `plot`.

### Details

All probes in `eset` that map to the given category are determined. Then per group, per probe means are computed and plotted against each other. Extra parameters can be passed to the plot function via the `dots` argument.

### Value

The matrix of per group means, for each probe.
