Issue with Traceplots inside of Map2stan

[rmcelreath]

These bugs remain mysterious, as no one has yet found out how to get a new system to produce them.

The underlying function in this case is tracerplot. You should be able to call it directly.

Thanks a bunch, using the underlying function worked.

I've encountered the same problem. I think there is an issue with the method definition, there is no plot.map2stan and therefore this class inherits from the default, which maybe does not support S4?

Hi, I get an error code with traceplot() as well. not sure if it is related:

Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function ‘traceplot’ for signature ‘"mcmc"’

I tried to plot an MCMCregress model.
