[R] Execution of R code

Greetings Folks,

When R code (as entered or read from a courced file) is executed,
is it interpreted from the input form every time having once been
read in, or do subsequent invocations use an "intermediate"
(pre-interpreted) form?

Or, putting it another way, is the execution of R code faster
second time time round (and later) because the pre-interpretation
has already been done once and for all?

[And, for seconds, what is the corresponding situation for S-plus?]

With thanks,
Ted.
