[Rd] R-exts.texi: suggestion for small change to Vignette section (PR#7323)

From: <S.J.Eglen_at_damtp.cam.ac.uk>

I recently wrote a vignette, with the following at the top of the .Rnw file:

%%\VignetteIndexEntry{How to use look up tables for h() functions} %%\VignetteDepends{sjedmin, spatstat}

Using vExplorer() on this function, I got an error from this part of getVigInfo():

    lines <- grep("^%[[:space:]]*\\\\Vignette", file)     if (length(lines) == 0)

        stop("File ", vig, " does not appear to be a vignette file, ", 
            "no vignette metadata available.")

The error occurs here because the grep expects only one % at the start of the line, whereas I had %%. (I often use two at the start of a line as I'm used to the ESS/Emacs coding habits of putting ## at the start of a line.) Changing %% to % solved the problem okay.

So, my minor suggestion to R-exts.texi, at line 1011:

@code{\VignetteIndexEntry} statement is best placed in La@TeX{} comment,

is that maybe it should say either:

"in a La@TeX{} comment"


"in a La@TeX{} comment with a single %"

although admittedly that sounds a bit clunky!

Thanks, Stephen
