Range breaks in plotly R

Hi,

Recently Plotly introduced breaks on date axes ( plotly v 4.6.0 ). They are pretty handy to remove weekends and missing dates while plotting. So far the fix was to make the Date as type =Category. But this makes the range slider not working. Thats also why this rangebreak was brought up. I dont know if its available in R yet.

A small workable script is given below

library(readr)
library(plotly)

a <- read_csv("https://raw.githubusercontent.com/plotly/datasets/master/finance-charts-apple.csv")

plot_ly(a[450:500,], x = ~Date, y = ~AAPL.High, type='scatter', mode = 'markers') %>%
  layout(xaxis =  list(
    rangebreaks= list (
      values= c("2016-12-25", "2016-12-24","2016-12-26","2017-01-01"))
  ))

Screenshot of the output:

This doesnt hide the missing dates, but it doesnt give any error either. I was wondering what am I doing wrong here.

Thanks

まず、plotly 4.9.2.1 で layout(xaxis = list(rangebreaks = ...)) を使用した付属の plot_ly() 例を実行し、その結果を Plotly の日付軸における rangebreak の動作と比較します。R-to-Plotly における xaxis rangebreaks の処理を追跡し、期待される結果が、動作する range slider を維持しながら欠落した日付を非表示にすることかどうかを明らかにします。
