plotPosteriors {baySeq} | R Documentation

## Plots the posterior likelihoods estimated for a 'countData' object against the log-ratios observed between two sets of sample data.

### Description

This function plots the posterior likelihoods estimated for a 'countData' object against the log-ratios observed between two sets of sample data. For those data where the log-ratio is infinite (because in one set of sample data all observed counts are zero), we plot instead the log-values of the other group.

### Usage

    plotPosteriors(cD, group, samplesA, samplesB, ...)

### Arguments

`cD` | A `countData` object, for which posterior likelihoods have been estimated (see `getPosteriors`).
`group` | From which group (as defined in the `'cD@groups'` slot) should posterior likelihoods be shown? Can be defined either as the number of the element in `'cD@groups'` or as a string which will be partially matched to the names of the `'cD@groups'` elements.
`samplesA` | A numerical vector giving the columns of data in the `'countData'` object that forms sample set A.
`samplesB` | A numerical vector giving the columns of data in the `'countData'` object that forms sample set B.
`...` | Any other parameters to be passed to the `plot` function.

### Value

Plotting function.

### Examples

    # We load in a `countData' object containing the estimated posterior
    # likelihoods of expression (see `getLikelihoods').

    data(CDPost)

    plotPosteriors(CDPost, group = "DE", samplesA = 1:5, samplesB = 6:10)

    # equivalent to plotPosteriors(CDPost, group = 2, samplesA = 1:5, samplesB = 6:10)
