[R-pkg-devel] Examples taking too long depend on object that takes a while to generate

John,
You have read_template, fetch_fit_example, yaml_read_fit and
build_figures taking up that time. Have you checked the individual timings?
If you are spending 27 seconds of user time on a small data set I'd wonder
what the full-scale times look like. I'd still be wondering whether you
have a non-linear ratio of processing cost to data size.

The examples don't need to process meaningful data, they are just examples
of what the code should look like.

if your absolute minimum time is still above 10 seconds you could
distribute a sample object under inst I suppose.

Hello Greg,

I'm already using a reduced dataset. I can reduce it a little bit further
but it doesn't really change things much.

John,
Can you cut the test data size back?  Do you have some processing costs
that are non-linear with data size?  27 seconds of user CPU is an awful lot
of processing these days.

Hello,

I'm working on submitting a new package. I've created examples for each
of
the functions. Most of these functions depend on an R object that uses
architecture-specific compiled code. To create that object can take
between
10-20 seconds. The function that creates it will cache it in the
tempdir().
So the first example that uses that object will take more than the 5
seconds allowed by CRAN. If I wrap that example in donttest, then the
next
function that uses it will exceed the 5 second limit, and on. I
submitted
the package with all of these examples wrapped in donttest, but that
got me
dinged :). So I'm trying to come up with a solution and I'd appreciate
any
help here.

Is there some way to build an object before tests are run?

Thank you,
John

If it would help this is an example where I'm testing it in win-builder:
