One of the projects I have been involved with is SeqNextGen, where I'm analysing exomes of patients who have a suspected rare genetic disorder. It's a change from what I was previously researching during my PhD; instead of working on an RNA level, I've reverse transcribed1 and I'm now examining DNA sequence and analysing genetic variants. There was a lot to learn to get started and I have written posts on "Getting started with analysing DNA sequencing data" and "Getting acquainted with analysing DNA sequencing data". I guess this is part three of the series where I'm "Getting serious with analysing DNA sequencing data2."
I saw this question on Quora:
A teacher assigns each of her 18 students a different integer from 1 through 18. The teacher forms pairs of study partners by using the rule that the sum of the pair of numbers is a perfect square. Assuming the 9 pairs of students follow this rule, the student assigned which number must be paired with the student assigned the number 1?
I recently completed Data Manipulation in R with dplyr and realised that dplyr can be used to aggregate and summarise data the same way that aggregate() does. I wrote a post on using the aggregate() function in R back in 2013 and in this post I'll contrast between dplyr and aggregate().
