[R-pkg-devel] Run-times of examples in vignettes

[Ben Bolker]

   My general solution is to run time-consuming computations in advance 
and store the results in (e.g.) inst/vignette_data, whence they can be 
retrieved via system.file("vignette_data", "output.rda", 
package="my_pkg"). (I might also include the R script required to 
generate the file so that I could automatically re-make those outputs as 
required ...)
