You do not need to know HTML to use Shiny, but if you do, you can use the methods in this article to enhance your app. The user-interface UI of a Shiny app is web document. Shiny developers can provide this document as an index. You can access this app by running:. Many Shiny apps come with a ui object that determines the layout of the app. You can see that the functions in the ui object definition return HTML if you run them. For example, the following code returns the HTML output in the comments below.
In R terminology, the output is a list of character strings with a special class that tells Shiny the contents contain HTML.
In a large majority of your Shiny apps, you will probably never think of using anything more complicated. However in some apps, you may want to add custom HTML that is not provided by the usual Shiny functions.
You can do this by passing HTML tags with the tags object. Each function builds a specific HTML tag. If you are familiar with HTML, you will recognize these tags by their names.
Style your apps with CSS
To create a tag, run an element of tags as a function. To create a div tag, you can run:. You can call some of the most popular tags with helper functions that wrap the appropriate tags functions. A tag function will use each named argument to add an HTML attribute to the tag. The argument name becomes the attribute name, and the argument value becomes the attribute value.
So for example, if you want to create a div with a class attribute, use:. Each tag function will add unnamed arguments to your tag as HTML children.But what if you are unfamiliar with HTML tags? The glossary below explains what the most popular tags in tags do.
You can use any of these functions by subsetting the tags list. For example to create an h1 header in HTML, run:. Some tags functions come with a helper function that makes accessing them easier. However, you can access many of the functions in tags only through tags because they share a name with a common R function.
The glossary below explains what the most popular tag functions do. The tag functions that do not appear here are less popular, but still useful. You can look them up at an HTML documentation site such as w3schools. Like in all R code, if you need to use a non-standard argument or variable name, you will also need to use backticks around it.
This can come up for attribute names, since a few of these will include dashes. For example, the following code will not work:. Creates a link to a web page. Creates text formatted as computer code. You can use the helper function code. Creates a section e. You can use the helper function div. Creates emphasized e.
You can use the helper function em. Adds hierarchical headings. You can use the helper functions h1h2h3h4h5h6. Adds a horizontal line e. You can use the helper function hr. Create a paragraph a block of text that begins on its own line. You can access the p tag with the helper function p too. Create pre-formatted text, text that looks like computer code.
Shiny from.Shiny includes a number of facilities for laying out the components of an application. This guide describes the following application layout features:. Segmenting layouts using the tabsetPanel and navlistPanel functions. Creating applications with multiple top-level components using the navbarPage function. The sidebar layout is a useful starting point for most applications.
This layout provides a sidebar for inputs and a large main area for output:. Note that the sidebar can be positioned to the left the default or right of the main area. For example, to position the sidebar to the right you would use this code:.
Rows are created by the fluidRow function and include columns defined by the column function. Column widths are based on the Bootstrap wide grid system, so should add up to 12 within a fluidRow container.
You can move columns to the right by adding the offset parameter to the column function. Each unit of offset increases the left-margin of a column by a whole column.
The offset parameter is used on the center input column to provide custom spacing between the first and second columns. Grid layouts can be used anywhere within a fluidPage and can even be nested within each other. You can find out more about grid layouts in the Grid Layouts in Depth section below. Often applications need to subdivide their user-interface into discrete sections.
This can be accomplished using the tabsetPanel function. For example:. Tabs can be located above the defaultbelow, left, or to the right of tab content.
For example, to position the tabs below the tab content you would use this code:. When you have more than a handful of tabPanels the navlistPanel may be a good alternative to tabsetPanel.
A navlist presents the various components as a sidebar list rather than using tabs. It also supports section heading and separators for longer lists. You may want to create a Shiny application that consists of multiple distinct sub-components each with their own sidebar, tabsets, or other layout constructs.
The navbarPage function creates an application with a standard Bootstrap Navbar at the top. Note that the Shiny tabPanel is used to specify the navigable components. You can add a second level of navigation to the page by using the navbarMenu function. This adds a menu to the top level navbar which can in turn refer to additional tabPanels. There are several other arguments to navbarPage that provide additional measures of customization:.R Shiny Tutorial - How to create Value Box in R Shiny Dashboard - R Programming Tutorial
There are two types of Bootstrap grids, fluid and fixed. Both grid systems use a flexibly sub-dividable column grid for layout. The fixed system occupies a fixed width of pixels by default and may assume other widths when Bootstrap responsive layout kicks in e. The following sections are a translation of the official Bootstrap 2 grid system documentation, with HTML code replaced by R code.

You can pass this argument in your call to plot. Inspired by this, in I wrote software to produce small multiple plots that incorporated this design among many others inspired by Tufte and Bill Cleveland's group and subsequently generated several million such graphics.
When you have to mine so much data visually, such principles really work. However, even in the absence of a rug plot you can choose where to stop and start drawing each axis.

Very simple question I hope! How can I edit the border-frame of these boxes? Will it require CSS or is there some short-hand code to remove borders?
