prompter

The goal of {prompter} is to easily create tooltips on many HTML elements in Shiny apps. This is the adaptation of hint.css in R.

Installation

You can install the CRAN version:

install.packages("prompter")

Or install the development version:

# install.packages("devtools")
devtools::install_github("etiennebacher/prompter")

Demo

library(prompter)
library(shiny)
library(ggplot2)
library(magrittr)

ui <- fluidPage(

  # Load the dependencies
  use_prompt(),
  
  column(
    3, 
    # Put the element inside add_prompt()...
    add_prompt(
      actionButton("plot", "click"), 
      position = "bottom", message = "this is a button"
    )
  ),
  column(
    9,
    # ... or use magrittr's pipe
    plotOutput("plot") %>% 
       add_prompt(
         message = "this is a plot, and I add some text to show the size of the box.",
         position = "left", type = "error", 
         size = "medium", rounded = TRUE
       )
  )
)

server <- function(input, output, session) {
  
  output$plot <- renderPlot(ggplot(mtcars, aes(wt, mpg))+ geom_point())
  
}

shinyApp(ui, server)
