Indenting new curly bracket blocks with smartparens for R

Emacs speaks statistics handle indentation for curly bracket blocks quite well. My preference was to have, after inserting matching opening and closing curly brackets, a newline with the cursor indented one block in. This post in particular describes the solution; it worked fine as of today.
Addendum: 2014-04-17
Here is the code snippet from the above link:

(sp-local-pair 'c++-mode "{" nil :post-handlers '((my-create-newline-and-enter-sexp "RET")))
(defun my-create-newline-and-enter-sexp (&rest _ignored)
  "Open a new brace or bracket expression, with relevant newlines and indent. "
  (newline)
  (indent-according-to-mode)
  (forward-line -1)
  (indent-according-to-mode))

Addendum: 2014-05-06
Here is a link to the documentation on using pre and post pair handlers.

Ten Simple Rules for Reproducible Computational Research

This link via irreal is another “must read” if you’ve never done systems work before (coming from a system person myself, not a data person).

Tidy Data

A huge amount of effort is spent cleaning data to get it ready for data analysis,
but there has been little research on how to make data cleaning as easy and effective
as possible. This paper tackles a small, but important, subset of data cleaning: data
“tidying”.

Tidy Data is a must-read paper.

Getting Started With R

Wrapping up the 2009-2010 School Year

This past May, I completed the Simulation and Parallel and Distributed Systems class that I was attending. While taking two classes while working full time was challenging; the pure fun of it all more than made up for the challenge! I will have fond memories of that semester for a long time.
I can’t wait to get started with Applied Mathematical Analysis next week.
