Re: [Rd] On RObjectTables
Maybe it is worth considering to document this functionality a bit more, or expose some wrappers in R? It's a bit obscure right now, which seems both dangerous in terms of maintenance and a missed opportunity (especially if people are already building on it).

Re: [Rd] On RObjectTables
In my original reply I wrote The facility in its current form does complicate the internal code and limit some experiments we might otherwise do, so I would not be surprised if it was at least substantially changed in the next year or two. This is obviously _not_ the time to invest effort in documenting or expanding this facility. If you want to use it, go ahead. But you will have to figure things out from what you have and be prepared for changes under your feet. If active bindings can do what you want that may be a safer route to consider. luke On Tue, 24 Jul 2012, Jeroen Ooms wrote: Maybe it is worth considering to document this functionality a bit more, or expose some wrappers in R?

Re: [Rd] On RObjectTables
I was thinking that the RObjectTables appeared before the active binding stuff was introduced. On quick examination, it seems the active binding mechanism might be a more stable way to go.

Usually the format is R CMD __what_to_do__ -flag options tarball.tar.gz. I.e., if I want to build xts, I get the source and run R CMD INSTALL xts_0.8-7.tar.gz and it all "just works." Linking uses -l as you noted, but only if you need libraries above and beyond the R headers (which are included automatically with R CMD install) that aren't in the package's */src directory. You'll see above the the appropriate flags were passed to gcc for you in specifing ATLAS and the gnu c99 extensions. Linking within R should be done properly for you.

Most likely it is simply not a UTF-8 character, but it could also be outside LaTeX's gamut. Normally the LaTeX log (which is in the check output) is more revealing: you can also try this part alone with R CMD Rd2pdf (and R CMD Rd2pdf --no-description often points the finger at the DESCRIPTION file).
