I am looking at this code, previously v-transformations were done and fitting VT-ARMA copula models, now here it is applying shapiro test to residuals and want to plot 4 graphs: https://i.stack.imgur.com/gTtBU.png
These 4 plots should come out of plot(vtcop, plotoption=3) etc... I have never used this argument plotoption, i think this argument is contained in the tscopula package ,but I have already done the necessary research on the help and read the pdf file that explains the tscopula package but there is no such "plotoption". Can anyone tell me why it tells me unused argument at this point? This code from by paper of AlexanderMcNeil: "Modelling Volatile Time Series with V-Transforms and Copulas". Thank you very much. Good day.
