Thank you all for the answers.
So if I may extend on the question -
When is it important to use 'Literal integer'?
Under what situations could not using it cause problems?
Is it a matter of efficiency or precision or both?
Thanks,

Efficiency: it avoids

This came up at least once before, with regard to where it is
documented:
http://r.789695.n4.nabble.com/Where-are-usages-like-quot-2L-quot-documented-tt831061.html
I haven't looked around much to see if the documentation has changed,
but in a quick look at ?integer I don't see the concept

Note however that I've never seen evidence for a *practical*
difference in simple cases, and also of such cases as part of a
larger computation.
But I'm happy to see one if anyone has an interesting example.
E.g., I would typically never use 0L:100L instead of 0:100

I've been wondering what L means in the R computing context, and was
wondering if someone could point me to a reference where I could read about
it, or tell me what it's called so that I can search for it myself. (L by

I encounter it in strange

Hi Gene,
It means 'Literal integer'.
So 1L is a proper integer 1, and 0L is a proper integer 0.
Hope it helps,

The notation '1L' mean to interprete the data as an 'integer'.
str(1)
num 1
str(1L)
int 1
str(0xaa)
num 170
str(0xaaL)
int 170

Thank you everyone, that makes a lot more sense now. It's not at all what I
would have guessed! (I thought that it might have to do with scope)
It's one of those little things would add just enough confusion that I would
sort of tune out whenever I saw it. So, I really appreciate having this
