quantile() type 1 for some ordered factors in R-devel
...) comes back NA
because of this:
https://github.com/cran/partykit/blob/597245ef3dfc98411ce919b74c68ba565f077c47/R/party.R#L500

time-consuming <https://twitter.com/trang1618/status/1260906905041432578>.
What about a warning whenever code that would trigger c.factor() is called?
This way users are given a chance to update packages and code.
Thanks,

quantile() type 1 for some ordered factors in R-devel
Hi,
In R-devel (2020-05-17 r78478) quantile() type 1 seems to behave a little
bit strange for some ordered factors:
quantile(factor(1:3, ordered = TRUE), 0.5, type = 1)
returns ?2? as expected. But
quantile(factor(2:4, ordered = TRUE), 0.5, type = 1)
returns ?4? and
quantile(factor(3:5, ordered = TRUE), 0.5, type = 1)
returns ?NA?. Furthermore, the function returns ?NA? for calls like
