There's 
no denying that for a language as popular as R, it has more than its fair share of quirks. If you've ever wondered why, for example, R has a non-standard assignment operator, or that periods are allowed in symbols (and don't signify method calls), or that character data imports as factors (not strings) by default, then this blog post by Oliver Keyes is for you. If you're new to R, it's worth checking out for some common traps in R's syntax. And if you're a longtime R user, it's an interesting (and entertaining) look into R's history, and how various influences (including ancient keyboards) have influenced the design of the world's most popular language for data science.
