[R] How to extrapolate a model

[Jannis]

I have no experience with this quantreg package and you did not include 
any code for us to reproduce your problem.

  But these models in R all work similar. Have a look at the model 
result object returned by the call of the fit (str(modelresults) ). I 
would expect that there is some formula component. Otherwise see what 
predict(modelresult), formulat(modelresults) fitted(modelresults) return 
( str() ) or have a look at the documentation of these functions.
