Stylize or format text in R Shiny Server

Question

I have an app running on shiny server and I would like to format smalls parts of text without needing to manage the css/html for the entirety of the page.

Simple example:

In the ui.r, I have some lines of help text that I would like to stylize.

sidebarPanel(
 ...
 , helpText("<I>Can</I> <em>this</em> <strong>happen</strong>?")
 )

Which gives:

# Current Output: 
<I>Can</I> <em>this</em> <strong>happen</strong>?

#desired Output:
Can this happen?

The text is (understandably) rendered as a literal string.
Is there a function or command to force the HTML to be parsed?

You maybe able to use the `HTML` function to prevent the HTML being escaped. — jdharrison, Sep 27 '13 at 17:57

Use this:

sidebarPanel(
 ...
 , HTML("<I>Can</I> <em>this</em> <strong>happen</strong>?")
 )

As an aside, you can even use renderText on the server side to build a full HTML output string, which can change, depending on your inputs. I often use this to post automated commentary (e.g. "The latest data release is y.... this is an increase of y, relative to the previous release...").

In regards to the aside, if I use `renderText` in the server to build an html string, like `my reactive headingmy reactive text` then how do I output that on the UI side? I tried `HTML(textOutput("theOutput"))` and that didn't work. Thanks! – seth127 Jan 02 '16 at 15:21
