As the OP, I will say that I had deduced that it probably was a way of specifying type integer, so I went to the ?integer page hoping for further info. I agree there should be some kind of short comment or see also at that page. I've been a self-taught user of R for about a year and a half, and this is one of the better hidden pieces of information. I had looked at the R Lang document, and probably should again for some additional ideas, but that was a long time ago. I did an RSiteSearch("1L") but not surprisingly this returns many uses of the feature, not the definition, at least not in the first few pages.
Thanks for the tips.
