plotly does not work with coord_radial

Released last year, coord_radial is the "new" way of producing polar plots in ggplot.

Unfortunately, we cannot use ggplotly with this method.

Example:

 p <- ggplot(mpg, aes(displ, hwy)) +
  geom_point() +
coord_radial(inner.radius = 0.3)

ggplotly(p)

results in:

Error in rng[[xy]]$get_labels() : attempt to apply non-function
In addition: Warning messages:
1: In min(z[["x"]]$dimension %()% z$x.range %||% z$x_range) :
no non-missing arguments to min; returning Inf
2: In max(z[["x"]]$dimension %()% z$x.range %||% z$x_range) :
no non-missing arguments to max; returning -Inf
3: In min(z[["y"]]$dimension %()% z$y.range %||% z$y_range) :
no non-missing arguments to min; returning Inf
4: In max(z[["y"]]$dimension %()% z$y.range %||% z$y_range) :
no non-missing arguments to max; returning -Inf

I assume this is linked to https://github.com/plotly/plotly.R/issues/878 but wanted to flag in case it's a separate issue.

Inizia eseguendo l’esempio R segnalato con coord_radial(inner.radius = 0.3) e ggplotly(p), quindi confronta il fallimento con il relativo issue 878 di plotly.R. Il lavoro è completo quando questo esempio viene convertito senza l’errore get_labels o gli avvisi associati di intervallo non valido.
