[R] About name of list elements

[Joshua Wiley]

Hi Max,

This is known as fuzzy matching.  When using `$`, if R can uniquely
match the element name based on what is typed, it returns it.  Thus,
in your example, foo uniquely matches foobar, but if you had foobar,
foobox, $foo would not be a unique match.

Cheers,

Josh
