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 [EMAIL PROTECTED] comment,
is that maybe it should say either:
"in a [EMAIL PROTECTED] comment"
or
"in a [EMAIL PROTECTED] comment with a single %"
although admittedly that sounds a bit clunky!
Thanks, Stephen
