Re: [Rd] Hidden files in source packages

Re: [Rd] include dll in R-package
Jeff, Thanks for the reply. For explicit dependency, can dll and functions be specified in namespace and imported by the package automatically? or the user has to use dyn.load and is.loaded to load the dll and functions in R? If it is the former, could you point me to an example that I could learn? Thanks!

You'll need to make that an explicit dependency, have some configure script and distribute the library somewhere else, but many packages on CRAN already do this. My RBerkeley uses a user installed Oracle Berkeley DB that is linked to at configure time, of course there are many other examples as well. And distributing _off_ CRAN is of course a reasonable alternative.

This is a CRAN Policy decision enforced by current R versions (but not the rather old version you compared against), and there is now way around it. You could try to construct defunct packages lacking the DLLs and instruct the users to get them from somewhere else, but that is at the same rather error prone (as you will lack all the built-time checks you would have with source code, as well as a better assurrance that compatible tools are used) and distasteful as CRAN is about Open Source. So your best bet may be to go back to the copyright holders Dirk's comments are extremely relevant if you were hoping to host the package on CRAN (which you basically won't be allowed to). You can still distribute it from your institutions homepage I think.

In that case, you do not want to have it in your NAMESPACE, since you just pass those data in a function call. Yet having it in a namespace would not cause any harm, wouldn't it ? Having it in a namespace would also have the added benefits: - loading up a dataset will not overwrite silently any existing dataset currently in .GlobalEnv - should an identical name for a dataset be found in several packages, one could refer to it with the :: operator. I am aware of the argument package to the function data(), but regret the apparent lack of general rule. - should one wish to list the objects defined (and eventually exported) by a package the use of one function would be sufficient. May be I am missing a fundamental point, but if my memory is correct the package datasets used to list its data objects when getNamespaceExports() was called.

[Rd] non portable filenames
I am including an external piece of software in an R package. This software ships with its own configure script generated by autoconf/automake, and this script is being run as part of the package configure script. The package contains a file m4/lt~obsolete.m4 which - as far as I can see - is a standard file from the autoconf/automake/m4 suite of programs. A warning is generated with R CMD check about this filename being non-portable. Presumably because of the ~ in the file name. The users is referred to the 'Package structure' part of R-exts. Reading the manual, I do not see ~ listed in the beginning of the paragraph where non-allowed characters are described. Quoting: To ensure that file names are valid across file systems and supported operating system platforms, the ASCII control characters as well as the characters ‘’, ‘*’, ‘:’, ‘/’, ‘’, ‘’, ‘?’, ‘\’, and ‘|’ are not allowed in file names. In addition, files with names ‘con’, ‘prn’, ‘aux’, ‘clock$’, ‘nul’, ‘com1’ to ‘com9’, and ‘lpt1’ to ‘lpt9’ after conversion to lower case and stripping possible “extensions” (e.g., ‘lpt5.foo.bar’), are disallowed. Also, file names in the same directory must not differ only by case (see the previous paragraph). In addition, the basenames of ‘.Rd’ files may be used in URLs and so must be ASCII and not contain %. However, ~ is also not part of the next sentence where allowed characters are listed. Quoting For maximal portability filenames should only contain only ASCII characters not excluded already (that is A-Za-z0-9._!#$%+,;=@^(){}'[] — we exclude space as many utilities do not accept spaces in file paths): non-English alphabetic characters cannot be guaranteed to be supported in all locales. It would be good practice to avoid the shell metacharacters (){}'[]$. To me it looks a bit like this paragraph is not self-consistent, since ~ is not listed as one of the characters already excluded. Now, I don't really know if ~ is portable. But I assume that the autoconf/automake/m4 people has thought a bit about this. And I don't really want to rename the file in question, as it is part of a lengthy configure script. So I guess my question is, is R CMD check correct in flagging the file? And what is recommended? I am tempted to ignore this warning, but I know warnings sometimes become errors. I assume other people might be in the same situation, since the filename originates from autoconf/automake/m4.
