[Rd] vignette optional sections.

I am writing a vignette that can run certain things on some systems but needs to skip them on other systems. (Some sections need databases that will not always be available.) Wrapping things in an if(){} partly works. It gives fairly ugly examples and all printing gets delayed until the end of the if. However, if the block produces a graphic, and I have {fig=TRUE} so in the case where the database is available the graphic is included in the vignette pdf, then the pdf generation fails in the case where the graphic is not produced.

Does anyone have suggestions for a nice solution to this?

Thanks,
Paul Gilbert
