Fast tau-estimator line does not appear on the plot
...#39;t
know what something means, that is usually a signal that you need to study
more... in this case about the difference between an input variable and a
design (model) matrix. This is a concept from the standard linear algebra
formulation for regression equations. (Note that I have never used RobPer,
nor do I regularly mess with model matrices, but I do recognize the term
"design matrix" and used help.search("design matrix") to track this down.)
Thanks for the reprex, though it is highly irregular to intersperse
install.packages in code that may be run more than once....

Any help would be highly appreciated.

abline() doesn't know what to do with the "fast" object. It isn't a
vector containing intercept and slope, it's a list containing them. So
you'll need someth...
