yes I think you are right, as I received similar answer from Uwe Liggs:

Given I remember correctly without looking into the details: It is the line number in the concatenated file (of all your .R files, by default sorted in a C locale).

Uwe added, there is no method known to him to determine in which file the problem is, and he recommended to post to r-devel. I'll do in a while if there is no answer in r-help, to avoid cross-posting.

Thanks to both of you!
