NULL.


Evaluate the first argument; if null, evaluate and return the
second argument.


This package implements workalikes for the author's (and
perhaps your) favorite features from other languages, making R
programs shorter and more expressive. Destructurimg bind lets you
perform parallel assignments and unpack nested lists. A chain
macro lets you quickly string several operations together, similar
to Unix pipelines. A collection of functions makes it easy to work
with `...` arguments and missing values. Behind the scenes is an
efficient macro utility, with a much improved alternative to the
bquote() function.
