Checks related to rebuilding the vignette from introduction.Rmd have failed, I'm not sure if changes made to coef.R might have affected that.

Probably. The problem is that you've made the only_nonzeros argument TRUE by default, so it'll have all kinds of unexpected consequences for tests and examples in the package, since coef() is used in several places.

Yep, thanks a lot for pointing that out. I have made the change.
