[R] rugarch package: VaR exceedances plot

[T.Riedle]

Dear all,

I am trying to backtest my VaR model in R using the rugarch package. Hence, I am trying to plot the VaR exceedances using following code from the rugarch package:

VaRplot(alpha=0.025,actual = returns,VaR = VaR,ylab = "daily log returns",xlab = "date")

Unfortunately, I get this error message and do not know the reason for this

Error in plot.window(...) : invalid 'ylim' value
In addition: Warning message:
In as.double.xts(actual) : NAs introduced by coercion

If I take the ylim error message into account I get the error:

Error in VaRplot(alpha = 0.025, actual = returns, VaR = VaR, ylab = "daily log returns",  : 
  unused argument (ylim = rangereturns)

Does anyone have an idea? Many thanks in advance.

Some hints at the following link where the "order.by requires an appropriate time-based object" error is commented.
