[R-pkg-devel] a problem with the underscore in a R function document

[Yaoyong Li]

Hello,

I just got a problem in a function document in a package I developed.The
file containing the document is generatingCDSaaFile.Rd. The problem is
related to the underscore I used in the following sentence

      and the last part is ‘\_AAseq.txt.gz’

I got a 'note' message when the package was checked in the CRAN:

checkRd: (-1) generatingCDSaaFile.Rd:72: Escaped LaTeX specials: \_

I don't think I saw this kind of message in the past (say six months
ago). A copy of the check result in CRAN is appended below. As you can
see, I also got the same problem in other places in the document. I
have been trying to fix the problem via searching Google. I have tried
to replace "\_" with "\textunderscore " as some internet post
suggested, but this did not solve the problem.

So I just wonder if anyone can help me with the problem. Please let me
know if any more information is needed.


Best regards,

Yaoyong
