Add HTML to a Shiny application and write its interfaces from scratch in HTML.Finally, you will learn how to lay out applications using a wide range of built-in functions.īy the end of the book, you will have an understanding of the principles that underpin layout in Shiny applications, including sections of HTML added to a vanilla Shiny application, HTML interfaces written from scratch, dashboards, navigation bars, and interfaces. Moving along, you will learn how to produce dashboards using the Shiny command and dashboard package. Furthermore, the book demonstrates the use of HTML templates and the Bootstrap framework. You will also learn to develop an application that creates documents and reports using R Markdown. You'll create a single application, but the interface will be reskinned and rebuilt throughout using different methods to illustrate their uses and functions using HTML, CSS, and JavaScript. The book starts by guiding you in producing an application based on the diamonds dataset included in the ggplot2 package. Hands-On Dashboard Development with Shiny helps you incorporate this in your applications. Get to grips with Bootstrap and leverage it in your Shiny applicationsĪlthough vanilla Shiny applications look attractive with some layout flexibility, you may still want to have more control over how the interface is laid out to produce a dashboard.Explore powerful layout functions to make attractive dashboards and other intuitive interfaces.Mutate(picture = ifelse(!is.na(image_url),Īs.Progressively explore UI development with Shiny via practical examples Key Features The true_false_formatter() defined below demonstrates how to define your own formatting function, in this case formatting TRUE, FALSE and NA as green, red and black. The cute heatmap-style colour formatting and the easy-to-use formatter functions make formattable very appealing.Ĭolor_tile() fills the cells with a colour gradient corresponding to the valuesĬolor_bar() adds a colour bar to each cell, where the length is proportional to the value Rownames = FALSE # don't show row numbers/namesĪnother nice table-making package is formattable. Selection = 'single', # enable selection of a single rowįilter = 'bottom', # include column filters at the bottom List(targets = c(0, 8, 9), visible = FALSE)) Server = FALSE, # use client-side processingĬolumnDefs = list(list(targets = '_all', className = 'dt-center'), ScrollY = TRUE, # enable scrolling on Y axisĪutoWidth = TRUE, # use smart column width handling ScrollX = TRUE, # enable scrolling on X axis PageLength = 15, # number of rows to output for each page Options = list(paging = TRUE, # paginate the output Here are some options that I find useful: datatable(villagers, More details about how these are implemented in DT is here and a full list of the options available in DataTables can be found in the DataTables documentation. These are passed to DataTables and interpreted as JS code. Note that while some customisation options belong as arguments to datatable, many others are ‘initialisation options’ that are passed to the options argument as named elements of a list. The resulting table already has really user-friendly features including pagination, searching, and sortable columns.
