Well, I know this is true for the default Sweave(), and my problem actually comes from the pgfSweave package: I used some tricks to "cheat" R to parse and deparse the code chunks so that the output can be automatically formatted (and preserve the comments, [1]). The price to pay for not being "honest" is these line numbers since R 2.12.0 (even if there are no errors in my code). As I am unable to figure out the logic behind Sweave() to generate line numbers, I cannot modify my code either. So a temporary dirty solution is to turn off the reporting of line numbers.
I wish the keep.source=FALSE option can preserve comments so that we don't need to touch utils:::RweaveLatexRuncode ([2]). Formatting the code chunks is really a nice feature with keep.source=FALSE, but the price of discarding comments is too high... I think the evaluate package might be a good place to look at (or perhaps the highlight package), which performs just like the R terminal (keep the comments and report the errors without really stopping R, [3]). Thanks!
