Its a 4 year old article and R has changed a TON with new things BUT.... R has grown a ton in users as well as features.

R really is a functional programming language that people don't take advantage on. All languages have strength and weaknesses and YET the complaint is R has too many ways to do any one thing which allows us to have data.table, dplyr, ggplot2, magrittr (pipping %>%). [EDIT RStudio and RServer are also a big example of R growth in features and quality]

As I learned R my code has changed dramatically and I think R has one of the largest gap between the code you start with and when you are proficient. My starting R code is really embarrassing.
