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 not required:
stats
Vignette dependencies (\VignetteDepends{} entries) must be contained in
the DESCRIPTION Depends/Suggests/Imports entries.
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,
