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 ...)

Seven minutes is excessive.
Sure. The one vignette contains simulation code which needs 1E5 to 1E6
sims to get a stable result. Fewer sims are simply not meaningful.
Since we use a pre-complied vignette now the execution time is
essentially zero.
The others take 45 seconds in total.
If we would pre-compile the second slowest as well, we would be down for
the remaining four at 12 seconds.
I have (long) gone by the rule of "about one minute" each for tests
and examples.
OK. Do you know of any reference for this "rule"?
Helmut
