Where does L come from?

Hi all,

Would someone mind pointing to me to the inspiration for the use of
the L suffix to mean "integer"?  This is obviously hard to google for,
and the R language definition
(https://cran.r-project.org/doc/manuals/r-release/R-lang.html#Constants)
is silent.

The link you have above, does reference the use of 'L', but not the derivation.

There is a thread on R-Help from 2012 ("Difference between 10 and 10L"), where Prof. Ripley addresses the issue in response to Bill Dunlap and the OP:

In searching, I also found the following thread on SO:

  https://stackoverflow.com/questions/22191324/clarification-of-l-in-r/22192378

which had a link to the R-Help thread above and others.

Regards,
