[R] [r] How to obtain the correlation coefficients between two variables in the R object

[Subhamitra Patra]

Thank you for your suggestion. Actually, the correlation is coming in the
DCC model through my above code which I am able to plot it. Is there any
solution that I can extract data from a particular plot. Actually, I am
able to obtain the correlation matrix, but I need the correlation
coefficient series indicating the correlation coefficients between the two
variables.
