`geom_quantile(method = "rqss")` does not seem to work with DEV version

Thanks for the report, David! I don't seem to be able to replicate the issue, it appears to work when I run that plot.

library(ggplot2)
packageVersion("ggplot2")

  ggplot(aes(x = flipper_length_mm,
             y = body_mass_g)) +
  geom_quantile(method = "rqss")

Thanks @teunbrand

I googled and stackoverflow said to reinstall MatrixModels library, and that seemed to work :)

@teunbrand I see this problem resurfacing in the on-line 'ggplot2' documentation for geom quantile. The solution remains the same as discussed above, reinstalling 'MatrixModels'.

This is resolved in the dev version, see https://ggplot2.tidyverse.org/dev/reference/geom_quantile.html
