Next: learn about how to easily select rows of data with interactive plots. While click, dblclick, and hover have x and y coordinates, brush is slightly different: because it’s a box, it has xmin, xmax, ymin, and ymax. plotOutput ( "plot1", click = "plot_click" )įor example, this app will print out the x and y coordinate position of the mouse cursor when a click occurs (to see it in action, click in the plot area of the app rendered below the code): library ( shiny ) ui <- basicPage ( plotOutput ( "plot1", click = "plot_click" ), verbatimTextOutput ( "info" ) ) server <- function ( input, output ) shinyApp ( ui, server ) Im trying to create a shiny app that will allow users to click on a point in the map, show where they clicked with a marker, allow them to label the point with a name (that they type in free text) and then save the latitude, longitude and label/name of all the. When two sets of coordinates are stored, it draws a line between the two points. When you double click on the image, it stores the coordinates in a dataframe. For example, this will define a new input value, input$plot_click, which contains the location of the previous mouse click. r shiny leaflet extract latitude longitude and label of markers to a dataframe. To get the position of the mouse when a plot is clicked, you simply need to use the click option with the plotOutput (). I have a shiny app here that loads an image, and has a 'dblClick' and a 'hover' method on the image. To get the position of the mouse when a plot is clicked, you simply need to use the click option with the plotOutput(). This makes it easy to add features like selecting points and regions, as well as zooming in and out of images. As of version 0.12.0, Shiny has built-in support for interacting with static plots generated by R’s base graphics functions, and those generated by ggplot2. Shiny - Control interactive plot point events clickOpts Control interactive plot point events Source: R/image-interact-opts.R Description These functions give control over the click, dblClick and hover events generated by imageOutput () and plotOutput ().
