Issue in plot_quantiles

[dannytoomey]

Hi Witold,

I was testing the plot_quantiles file got the following error when running the function example:

> bg <- baggr(microcredit_simplified, model = "quantiles",quantiles = c(0.25, 0.50, 0.75),iter = 1000, refresh = 0,outcome = "consumption")
Error in out$Nc <- 0 : object 'out' not found

Should we add this one to the list? Looks it might be a stan error.

Best regards,

Danny Toomey
