?NumericConstants
will bring up a help page that mentions
"All other numeric constants start with a digit or period and are either a decimal
or hexadecimal constant optionally followed by L."
and
"An numeric constant immediately followed by L is regarded as an integer number when possible
(and with a warning if it contains a "."). "
but I haven't found discussion of it anywhere else in the help pages.
Others may know what other help pages discuss this.
I'm surprised that the help page invoked from
?integer
does not discuss this. Anyone know why not?
This is part of the syntax of the language. It has nothing to do with
the integer() function, which is what ?integer is asking about.

Subject: [R] Where are usages like "== 2L" documented?
Gurus:
I keep seeing other people¹s code that contain ideas like
If (x == 2L)
X[-1L]
X - 1L
I have some idea of what¹s going on, but where is the use of concepts
like
³2L² documented?
Thanks, Bryan
