How to post R code on WordPress blogs

Most WordPress BloggeRs are using this text highlight syntax, some are not.
I hope that this post would be a reference source for new WordPress BloggeRs for posting their R code on their blog posts.

According to an official guide by WordPress.com on “Posting Source Code“, To post R code in the WordPress.com, just wrap R code as follows (without “#” in both wrappers):

######################################################

[#sourcecode language="r"]
Your R code and comments
x <- rnorm(100)
y <- x + 10
[#/sourcecode]

######################################################

• From above, before your R code put the command in line 1, or [#sourcecode language=”r”], but without #
• Then, place your R code (line 2-4).
• End the code box by put the command line as in line  5, but without # or “[/sourcecode]“

Then the code will appear as following.

Your R code and comments
x <- rnorm(100)
y <- x + 10

Moreover, more options can be configured to better describe the code efficiently.

• autolinks (true/false)
  TRUE: Makes all URLs in your posted code clickable.
  Defaults: TRUE
• collapse (true/false) 
  TRUE: The code box will be collapsed when the page loads, requiring the visitor to click to expand it.
  Comment: Good for large code posts.
  Defaults: False.
• firstline (number)
  Comments: Use this to change what number the line numbering starts at
  Defaults =  1
• gutter (true/false)
  TRUE:  Show the line numbering on the left hand side.
  FALSE: The line numbering on the left side will be hidden.
  Defaults = TRUE
• highlight (comma-seperated list of numbers)
  You can list the line numbers you want to be highlighted.
  Example = “4,7,19″.
• htmlscript (true/false)
  TRUE: Any HTML/XML in your code will be highlighted.
  Comment: This is useful when you are mixing code into HTML, such as PHP inside of HTML.
  Defaults = FALSE (only work with certain code languages)
• light (true/false)
  TRUE: The gutter (line numbering) and toolbar (see below) will be hidden.
  Comment: This is helpful when posting only one or two lines of code.
  Defaults = FALSE
• padlinenumbers (true/false/integer)
  TRUE: Automatic padding
  FALSE: No padding, and entering a number will force a specific amount of padding.
  Comment: Allows you to control the line number padding.
• toolbar (true/false)
  FALSE: The toolbar containing the helpful buttons that appears when you hover over the code will not be shown.
  Defaults = TRUE
• wraplines (true/false)
  FALSE: Line wrapping will be disabled. This will cause a horizontal scrollbar to appear for long lines of code.

If you are using WordPress.org, here is a plugin.
