First and foremost, I would like to thank you for such a great package. The accompanying paper is also such a great addition.
Given that the package's authors chose to not have a formula interface, I would like to know if there is any way to include interaction terms. It is possible to create the interactions myself in the data; however, I suspect that the output will contain incorrect coefficients and standard errors for the terms which are not interactions.
