everyone will write a blog post on dplyr

dply is a nice R package to manipulate big data. There are several good tutorials I came across:

I followed the example in the early edition of Bioinformatics Data Skills on the dplyr part and put a gist below. The example used dplyr to manipulate and summarize the human annotation gff file downloaded here

I downloaded the ensemble 74 build which is different from the 75 build in the example of the book.
I believe the gencode v19 annotation file is based on ensemble 74.

I also included comments in the R code describing how to do the same job with linux command line.
