Writing raw HTML is a crime against humanity, so as writing raw HTML with R. Tags $ figcaption ( HTML ( "Photo by Alison PangĪfter keep revising the paragraphs for a few times, I decided this will be too dumb to write raw HTMLs again and again. I believe no one wants to redad and write something like In markdown, I could just write _italic_ and _bold_. Writing bold and italic is troublesome: I have to write so many tags$b and tags$i and cut the whole sentence into various chunks. "" as \" \" ) in order to escape the colon marks, just like escaping special characters in LaTeX and MathJax Writing special characters requires trailing backslash (e.g. This does the job, but annoys me (at least) in the following aspect: Residence and work as fellows: " ), tags $ ul ( tags $ li ( tags $ mark ( "Same area (Hong Kong Island/Kowloon/New Territories)", style = "color:#ffffff background-color:#4daf4a" )), tags $ li ( tags $ mark ( "Between Hong Kong Island and Kowloon", style = "color:#ffffff background-color:#377eb8" )), tags $ li ( tags $ mark ( "Between Hong Kong Island and New Territories", style = "color:#ffffff background-color:#ff7f00" )), tags $ li ( tags $ mark ( "Between Kowloon and New Territories", style = "color:#ffffff background-color:#984ea3" )) ), The color of the flows are classified according to the location of place of The thicker the flow, the more workers are Living/working pair from the selected place of residence and work.

So this is how it looks when using the tags function to write the same paragraphs: I: Introduction Instead of writing paragraph or H2 title, you need to write p("paragraph") and h2("H2 title"). You need to wrap the text using the equivalent html tag. How to write the same paragraphs in a shiny web app? htmltools package provides some HTML Builder Functions for constructing HTML documents. Same area (Hong Kong Island/Kowloon/New Territories) - Between Hong Kong Island and Kowloon - Between Hong Kong Island and New Territories - Between Kowloon and New Territories Hover and click over the flows to check how many workers are in that living/working place combination.įormatted html output when view in browser The *colour* of the flows are classified according to their travel patterns as follows: The *thicker* the flow, the **more workers** are in that living/working location pair. Each flow represents a combination of living and working place. In the middle, there have a bunch of 'flows' meandering from left to right. The bar on *left* group the workers by their **living place**, while the *right* group by their **working place**. The two sides of the chart resembles two stacked bar charts showing the total number of workers. Note that this only applies to snippets of Shiny code during an interactive Rmd (and not to embedded full apps - the ones you need to call `shinyApp` to run).The chart below is a **sankey diagram**. This means that you don't have to create a `ui` object just to be able to brush over an image. To give an example, this allows you to set arguments to `imageOutput` through `renderImage`. title: Setting output args via render functions runtime: shiny output: html_document - This interactive Rmd document makes use of the `outputArgs` argument now available to all Shiny `render` functions. For example, suppose that you want to render a plot and specify its width to be 200px and height to be 100px. To pass options from renderXXX() to xxxOutput(), you can use the outputArgs argument, if it is available to specific renderXXX() functions. In particular, plotOutput() can take in some optional arguments to set things like width and height, or allow you to click or brush over the plot (and store that information). However, some functionality can be lost in this process. In this case, Shiny helpfully associates the corresponding output object to each renderXXX() function, letting you use Shiny code outside of a full Shiny app. For example, you may want to use a renderPlot() function without having to create a plotOutput() slot beforehand. In a typical Shiny application, you specify an output element in the UI using functions like plotOutput() and verbatimTextOutput(), and render its content using functions like renderPlot() and renderPrint().īy comparison, in a Shiny document, the UI elements are often implicitly and automatically created when you call the renderXXX() functions. 19.7 Output arguments for render functionsġ9.7 Output arguments for render functions.16.5.4 Create a widget without an R package.2.1.4 2017 Employer Health Benefits Survey.
