Extracting stan code from stanarm

[Kurtis Goad]

So, is it supposed to take an eternity to extract the stan code from a model made with the stanarm function? 

I'm trying to figure out if its worth waiting for (still waiting after almost half an hour) or if I should just take a sample from the data and try a model with that instead of the whole 4800 something in the original data set...

Probably best to move on...

Cheers,

So I have a smaller sample of the data now but when I run the get_stancode() function I keep getting this error message:

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

My guess is this is because the model is a stanreg object rather than a stanfit object but I can't figure out how to make a stanfit object rather than stanreg when using rstanarm

Heres the code I used:

model100 <- stan_lm(difi_paro ~ dgOffer, data=data100, prior = NULL)
get_stancode(model100)
