possible bug in R CMD Rd2pdf

5 messages · Peter Dalgaard, Kasper Daniel Hansen, Duncan Murdoch

When I include the macros \packageAuthor, \packageDescription,
\packageTitle, \packageMaintainer in a XX-package.Rd file, R CMD Rd2pdf
fails with

$ R CMD Rd2pdf mpra
Hmm ... looks like a package
Converting Rd files to LaTeX Error : mpra/man/mpra-package.Rd:6: file
'./DESCRIPTION' does not exist

This does not happen if I comment out 4 occurrences of these 4 macros in
mpra-package.Rd.

This is with

R Under development (unstable) (2017-09-26 r73351) -- "Unsuffered
Consequences"
Copyright (C) 2017 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin16.7.0 (64-bit)

or

and MacTex 2017.

Best,

If it is looking for ./DESCRIPTION, perhaps it matters which directory you invoke it from?

-pd

Those errors are coming from tools:::Rd_package_author and related 
functions, because the system-defined macros call them.  Current 
definition of the \packageAuthor macro is

\newcommand{\packageAuthor}{\Sexpr[results=rd,stage=build]{tools:::Rd_package_author("#1")}}

and the function is defined as

function (pkg, dir = ".")
{
     desc <- .read_description(file.path(dir, "DESCRIPTION"))
     if (pkg != desc["Package"])
         stop(gettextf("DESCRIPTION file is for package '%s', not '%s'",
             desc["Package"], pkg))
     desc["Author"]
}

So Peter is right, this would likely work if the current working 
directory was the top level directory of the package, but it can't work 
in general.

The easiest fix would probably be to change the code underlying R CMD 
Rd2pdf so that it works from the top level directory; another 
possibility might be to come up with a better default for the "dir" 
parameter.

Sorry for the noise.

I assumed I could run this in the same directory as R CMD check. If I cd
into the package dir, and run it like
  R CMD Rd2pdf man
it works. I was a bit sleep deprived yesterday.

The fact that the output starts by
  Hmm ... looks like a package
threw me off. That output suggests it should work, I think. So I would
suggests either
  1) handling both package and man directories
  2) check that the input dir is a collection of man pages with a
DESCRIPTION file in the same directory

Best,
Kasper

I wouldn't call this noise, it's a bug that happens to have a fairly 
easy workaround.  The tools functions are mainly for use by R utilities, 
so they sometimes make strong assumptions about the context in which 
they are used; this is a case where something that was thought of as 
internal leaked out into user-land.
You could also use

R CMD Rd2pdf .

while in that directory.
