R shiny gauge chart

Question

Could someone help me draw a gauge chart in R Shiny?I don`t need it to be dynamic, but to have a KPI that I assign with a value and to show that when I run the app.It should be red from 0 to 0.3, yellow from 0.3 to 0.5 and green from 0.5 to 1.

flexdashboard provides such a gauge chart:

library(shiny)
library(flexdashboard)

ui <- fluidPage(
  numericInput("value", label = "Select value", min = 0, max = 1, value = 0.5, step = 0.1),
  gaugeOutput("gauge")
)

server <- function(input, output) {

  output$gauge = renderGauge({
    gauge(input$value, 
          min = 0, 
          max = 1, 
          sectors = gaugeSectors(success = c(0.5, 1), 
                                 warning = c(0.3, 0.5),
                                 danger = c(0, 0.3)))
  })
}

shinyApp(ui = ui, server = server)
