I would like to create a column or bar chart with pattern fill in an R shiny app. It seems to me that highcharts and related highcharter package should be able to do the job, but I could not find a way. Here is what I tried based on this page:
https://www.highcharts.com/docs/chart-design-and-style/pattern-fills

    library(highcharter)



hchart(iris,
       type = "column",
       hcaes(x=Species, y=Sepal.Length))%>%
  hc_plotOptions(
    series = list(
      borderColor = "blue",
      color= list(
        patternIndex = 0
      )
    )
  )
