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

1
2
3
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.
