2.rcor(cfit) returns an array of the conditional correlation. 3-4 Try searching first on http://www.rseek.org/.
Finally, the 'rmgarch.tests' folder in the installation directory of the package contains many examples which you might find helpful.

Hi I am trying to implement a typical GARCH-Copula with DCC for dynamic correlations. Is there someone could give me an example codes how it can be done? I have implemented this in Matlab, but don't know how to get a start in R. I have googled around and found rmgarch package can give it a go. Below is what I did:library(rmgarch) data(dji30ret) Data<- dji30ret[, 1:3, drop = FALSE] uspec<- ugarchspec(mean.model = list(armaOrder = c(0,0), include.mean = FALSE), variance.model = list(garchOrder = c(1,1), model = "sGARCH"), distribution.model = "std") cspec<- cgarchspec(uspec = multispec( replicate(3, uspec) ), VAR = FALSE, robust = FALSE, lag = 1, lag.max = NULL, lag.criterion = c("AIC", "HQ", "SC", "FPE"), external.regressors = NULL, robust.control = list(gamma = 0.25, delta = 0.01, nc = 10, ns = 500), dccOrder = c(1, 1), asymmetric = FALSE, distribution.model = list(copula = "mvt", method = "ML", time.varying = TRUE, transformation = "parametric"), start.pars = list(), fixed.pars = list()) cfit<- cgarchfit(cspec, data =Data, spd.control = list(lower = 0.1, upper = 0.9, type = "pwm", kernel = "epanech"),fit.control = list(eval.se = TRUE, trace = TRUE, stationarity = TRUE),solver = "solnp", solver.control = list(), out.sample = 0, parallel = FALSE, parallel.control = list(pkg = c("multicore", "snowfall"), cores = 2), fit = NULL, VAR.fit = NULL)my questions are: 1) (very silly) how to get the estimated parameters (incl. s.e. p-value)? 2) how to plot the dynamics of correlation? 3) how to perform goodness-of-fit tests for marginal estimations? 4) how to perform goodness-of-fit tests for copula? I will appreciate for any help!
