Could anyone refer to me to a good source to learn how to program a simple
control-flow construct* in R, or provide me with a simple example?
Control-flow constructs are programmed as primitives, but I would like to
be able to do that (if possible) in pure R.
The general context is that those functions are a mystery to me. The
motivating example is that I would like to create a function that behave
similarly to base::`if` with an extra argument to the function (e.g. to
include an error rate on the condition).
* control-flow constructs are functions such as if, for, while... that
allow for call of the form fn(x) expr to work (see ?Control).
