expressions

Days 26-27: Expressions

A few days ago I postedabout my first attempt to understand metaprogramming in R, trying to wrap my head around non-standard evaluation with the help of Hadley Wickham’s Advanced R book. That was a lot of fun. This time around, it’s the expressions section – well the first half of it anyway 😀 – and an attempt to go through the looking glass and understand what is going on internally with R expressions.
