Drapery argument #18
Description
How should the drapery lines be specified? Currently this is just a binary argument but the meta-analysis drapery line in autoplot(..., type = "p") is restricted to either "fe" or "re" but since this line just depends on the MA CI, we could also do this for "hk" or "hc". Thus, the question remains how we could possibly include more than one option and make them have different colors.
Thoughts:
- vectorise get_drapery_df() over all MA methods
- add a color for each. Problem with that: How to specify colors? Should be user adjustable and consistent with the forestplot.
