Be careful when deciding which variable is the explanatory variable and. See help for more help with all things Shiny. Use the function, plot(explanatoryvariable, responsevariable) to draw the scatterplot. Our developers monitor these forums and answer questions periodically. If you have questions about this article or would like to discuss ideas presented here, please post on RStudio Community. pairs(disp + wt + mpg + hp, data mtcars) In addition, in case your dataset contains a factor variable, you can specify the variable in the col argument as follows to plot the groups with different color.

Next: learn about how to easily select rows of data with interactive plots. 3) Example 2: Add Labels to ggplot2 Scatterplot. 2) Example 1: Add Labels to Base R Scatterplot. To be more precise, the table of content looks like this: 1) Creating Example Data. The article consists of three examples for the addition of point labels.

The second code is for calculating the mean and standard deviation. In this post, I’ll explain how to add labels to a plot in the R programming language. Anyway, Ill insert my database image at the end of this message. The link to download the database is: databasetest.xlsx - Google Sheets. 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. I will insert two codes below, the first one generates a scatter plot that takes into account the chosen date ( date2) in my database. 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 ) For example, this will define a new input value, input$plot_click, which contains the location of the previous mouse click. lessR provides many versions of a scatter plot with its Plot() function for one or two variables with an option to provide a separate scatterplot for each. 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.
