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.

首先使用 coord_radial(inner.radius = 0.3) 和 ggplotly(p) 运行报告的 R 示例，然后将该失败与相关的 plotly.R issue 878 进行比较。当此示例能够转换且不出现 get_labels 错误或相关的无效范围警告时，工作即告完成。
