What is the saying… “you’ll find the error just after you click submit”…?
Anyways, it seems the problem is not the estimation of the model, only in displaying the result. I guess somehow the RObject{VecSxp} does not want to be printed. If I instead do @rget objectname then it gets converted to a DataFrame fairly quickly and is printed without issue. Happens in the terminal too. I suppose I will post an issue in RCall.jl.
