## Writing files in CODA format

### Description

This function writes files in CODA format to be processed or imported, e.g, by some other software.

### Usage

    samplesCoda(node, stem, beg = samplesGetBeg(),
        end = samplesGetEnd(), firstChain = samplesGetFirstChain(),
        lastChain = samplesGetLastChain(), thin = samplesGetThin())

### Arguments

`node` | Character vector of length 1, name of a variable in the model.
`stem` | The filestem of the CODA files to be generated. See details.
`beg, end` | Arguments to select a slice of monitored values corresponding to iterations `beg:end`.
`firstChain, lastChain` | Arguments to select a sub group of chains.
`thin` | to only use every `thin`-th value of the stored sample.

### Details

Example for argument `stem`: If `stem = "c:/myFolder/foo"`, the resulting files are called ‘`fooCODAchain1.txt`’, ..., ‘`fooCODAchainN.txt`’, and ‘`fooCODAindex.txt`’. They are written into the `tempdir()` and copied to the path ‘`"c:/myFolder"`’.

If the variable of interest is an array, slices of the array can be selected using the notation `variable[lower0:upper0, lower1:upper1, ...]`.

If the arguments are left at their defaults the whole sample for all chains will be used for output.

### Value

Prints ‘CODA files written’.

### Note

If the MCMC simulation has an adaptive phase it will not be possible to make inference using values sampled before the end of this phase.
