R devel - Jul 2007 - possible bug R CMD check: No space(s) allowed after \VignetteDepends{}

R CMD check gives an error when a vignette entry %\VignetteDepends{} has any
extra space at the end.
Maybe this is by design, but I found it confusing.

Changing the function "vignetteMetaRE" in tools package could solve
the
problem. I.e.

vignetteMetaRE <- function(tag)
    paste("[[:space:]]*%+[[:space:]]*\\\\Vignette",
tag,"\\{([^}]*)\\}", sep
= "")

becomes:

vignetteMetaRE <- function(tag)
    paste("[[:space:]]*%+[[:space:]]*\\\\Vignette",
tag,"\\{([^}]*)\\}[[:space:]]*", sep = "")



Details:

The test package I'm using has only one vignette:

\documentclass[oneside,letterpaper,12pt]{book}
%\VignetteIndexEntry{some entry}
%\VignetteDepends{stats}
%\VignetteKeyWords{mymodel}
%\VignettePackage{testpkg}
\begin{document}
<<test>>print("test")
@
\end{document}

R CMD build, R CMD check and R CMD INSTALL run successfully.

If I add an extra space after %\VignetteDepends{stats} then "R CMD
check"
fails

w5:falimadh [~/work/mypkg]> R CMD check testpkg

Vignette dependencies (\VignetteDepends{} entries) must be contained in

See the information on DESCRIPTION files in the chapter 'Creating R
packages' of the 'Writing R Extensions' manual.
----------------------------------------------------------------------

The error message is from tools:::.check_package_depends() function
which is used by R CMD check.
check_package_depends() calls .build_vignette_index() to get the vignettes
dependency list
For my test package, the result is:
> reqs <-
unique(unlist(tools:::.build_vignette_index("testpkg/inst/doc/")$Depends))
> reqs
[1] "stats "
>
"stats " (with a space at the end) is not in the depend field of my
package
description ("stat" is). And that's where the error comes from.


Does this make sense ?

Thanks,
Ferdi

Actually, this is by design, but I'll look into changing it.
