This function writes files in CODA format to be processed or imported, e.g, by some other software.
samplesCoda(node, stem, beg = samplesGetBeg(), 
    end = samplesGetEnd(), firstChain = samplesGetFirstChain(), 
    lastChain = samplesGetLastChain(), thin = samplesGetThin())Prints ‘CODA files written’.
Character vector of length 1, name of a variable in the model.
The filestem of the CODA files to be generated. See details.
Arguments to select a slice of monitored values corresponding to iterations beg:end.
Arguments to select a sub group of chains.
to only use every thin-th value of the stored sample.
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.
