[R] recommendations on use of -> operator

[Emmanuel Charpentier]

An old (Lisp ? C ?) quote, whose author escapes me now, was :

"syntactic sugar causes cancer of the semicolon"

.. but nowadays semicolons are rarely used in "real-life" R.

					Emmanuel Charpentier

PS and, BTW, neither C nor Lisp have much use for semicolons... Was that
Pascal (or one of its spawns) ?
