This function calculates the correlation matrix between two vectors of variables.
samplesCorrel(node0, node1, beg = samplesGetBeg(),
end = samplesGetEnd(), firstChain = samplesGetFirstChain(),
lastChain = samplesGetLastChain(), thin = samplesGetThin())Correlation matrix.
Character vectors of length 1, name of variables in the model.
Arguments to select a slice of monitored values corresponding to iterations beg:end.
Arguments to select a sub group of chains to calculate correlation(s) for.
to only use every thin-th value of the stored sample for statistics.
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 calculation.
