How do I fix the unrecognized object error in Stargazer with a dynlm model?

Question

I calculated a dynlm model and now want to get stargazer to export that. However, stargazer does not return any output, instead gives me the Unrecognized object type Error. I already checkd if dynlm objects were supported by stargazer and according to the package page it is. Anyone have any idea what I'm getting wrong here? I know how to export the output with stargazer, but in this case it doesn't even show me the results inside of R. This is the model I used and the stargazer command, which returned the error. Really need your help! Thanks in Advance for any suggestions :)

model1 <- dynlm::dynlm(zz$AverageCONS~zz$GDPGrowth + zz$BRGOVMEHR, zz)
 summary(model1)

This is the dput for the regression!

Answer 1

There are several problems:

1. By writing dynlm::dynlm the dynlm package is only known at that point but not by stargazer.
2. zz should not be used in the formula.

Write it like this:

library(dynlm)
library(stargazer)

model1 <- dynlm(AverageCONS ~ GDPGrowth + BRGOVMEHR, zz)
stargazer(model1)
