corelement extracts the model-implied (time-varying) correlations between
(exactly) two component series.
corelement(x, i, j, these = seq_len(nrow(x$y)))Vector with the requested correlations.
Object of class 'fsvsim', usually resulting from a call
of the function fsvsim.
Index of component series 1.
Index of component series 2.
Vector indicating which points in time should be extracted.
