Issue with next version of ggbeeswarm

Hi @singmann, I am working on releasing a new version of ggbeeswarm and am encountering a similar issue when CRAN performs its reverse-dependency checks:

--- re-building ‘afex_plot_supported_models.Rmd’ using rmarkdown
 Quitting from lines 245-247 (afex_plot_supported_models.Rmd) 
 Error: processing vignette ‘afex_plot_supported_models.Rmd’ failed with diagnostics:
 Problem while computing position.
 ℹ Error occurred in the 1st layer.
 Caused by error in `if (method %in% c("swarm", "compactswarm")) ...`:
 ! argument is of length zero

This appears to be related to the extdata/plots_rstanarm.rda file loaded in line 245. There are no other errors in the vignettes, which leads me to believe this error is related to changes in the internal plot objects and not from any changes to the ggbeeswarm interface.

I can also confirm that this error occurs using both the CRAN version of afex and the most recent version on Github.

Thanks for the report, fixed now and on its way to CRAN
