Any chance someone (Hadley and Garrett) are working on a new version of the r4ds book that uses ggvis instead of ggplot2? Can I get a preview version?
ggvis is dormant so I don't see any chance of this happening for some time.
See this thread:
2018 is the year of Gee... Gee Whiz...
Just kidding. I don't think it would make since to add ggvis to R4DS until more development occurs on ggvis. Even then, ggvis won't replace ggplot2. In the mean time, I have a DataCamp course on ggvis.
