Error in ifelse() with plot object #57

Hi there!

We're preparing a new release of ggplot2 and during a reverse dependency test, it became apparent that your package was failing with the new version.
In this case, we believe this is a bug in the fairmodels package, in particular in the lines below:

In this case, it appears you're using ifelse() on a plot object. A plot object is not a vector, so I'll suggest to use the if () {} else {} control logic, instead of the ifelse() function.
We plan to release the new ggplot2 version in a few weeks, at which point CRAN might start complaining about this.
Hopefully this informs you in a timely manner.

Best wishes,
Teun
