The R package wrapr supplies a few neat new coding notations. An Abacus, which gives us the term “calculus.”
In this article we will discuss composing standard-evaluation interfaces (SE: parametric, referentially transparent, or “looks only at values”) and composing non-standard-evaluation interfaces (NSE) in R. In R the package tidyeval/rlang is a tool for building domain specific languages intended to allow easier composition of NSE interfaces. To use it you […]
I recently read an interesting thread on unexpected behavior in R when creating a list of functions in a loop or iteration. The issue is solved, but I am going to take the liberty to try and re-state and slow down the discussion of the problem (and fix) for clarity. […]
Let’s take a break from statistics and data science to think a bit about programming language theory, and how the theory relates to the programming language used in the R analysis platform (the language is technically called “S”, but we are going to just call the whole analysis system “R”). […]
R is a statistical analysis package based on writing short scripts or programs (versus being based on GUIs like spreadsheets or directed workflow editors). I say “writing short scripts” because R’s programming language (itself called S) is a bit of an oddity that you really wouldn’t be using except it […]
