prodplot (from package
productplots) seems not to work any more.
prodplot(happy, ~ sex + happy, c("vspine", "hbar"))
produces an error
Error: `b` = l must be a symbol or a string, not formula
As a consequence, geom_mosaic from ggmosaic produces the same error.
How can I make it work again?
I am using R 3.4.2 on MacOS 10.13.1 in RStudio 1.1.393
productplots version 0.1.1.9000 from github.
It also breaks with the version from CRAN (0.1.1)
