Dear all,
I would like to plot credible interval for a function estimate in R. I
would like to plot the credible intervals as shaded region using polygon
function. Does anyone ever used that? I tried several times but I could
not obtain the right figure.



The above piece of code produces something else.

Many thanks in advance,
