Hi Tim, Here's a rather long thread from previous discussions of this:
https://stat.ethz.ch/pipermail/r-devel/2014-May/069113.html These two lines from R CMD check suggest the two ways the vignette code will be run: * checking running R code from vignettes ... OK * checking re-building of vignette outputs ... OK Chunk option `purl` controls whether a chunk is extracted and rerun during “running R code from vignettes”. Chunk option `eval` controls whether a chunk is run during the “re-building of vignette outputs”. Perhaps your benchmarking code is still being extracted and run during the purl (a.k.a. "tangle") phase. -- Jenny On Mon, Mar 19, 2018 at 8:04 PM, Tim Keitt <tke...@utexas.edu> wrote: > http://www.keittlab.org/ > > On Mon, Mar 19, 2018 at 6:41 AM, Dirk Eddelbuettel <e...@debian.org> wrote: > > > > > On 18 March 2018 at 21:57, Tim Keitt wrote: > > | That's a great idea, however my problem is with building a vignette, > not > > | running tests, unless they are linked in some way I'm not > understanding. > > > > Similar idea applies: condition, just as Inaki and Thierry suggested.
