The use of tags in UI.R

tags is an object of type list that is automatically generated inside Shiny applications, which enables the insertion of HTML tags within a user interface generated in UI.R. This basically contains a list of functions that will transform the string argument to the content of the tag used, for example, see the following:

tags$pre("Text inside a pre tag")

This generates the following tag:

<pre>Text inside a pre tag</pre>

Note

The complete list of tags can be found at http://shiny.rstudio.com/articles/tag-glossary.html.

tags$pre(align="right","Text inside a pre tag")

This will be turned into the following HTML:

<pre align="right">Text ...
