devtools' reference output for examples

When I was about to use the examples' output (examples from .Rd files) as a reference output, I noticed that the reference output produced by devtools is different to what a plain R CMD check produces. Notably, the file pkg_name-Ex.Rout (to be stored at /tests/Examples/pkg_name-Ex.Rout.save) contains a bunch of line like these which are not in the same file generated by R CMD check:

base::assign(".ExTimings", "pkg_name-Ex.timings", pos = 'CheckExEnv')
base::cat("name\tuser\tsystem\telapsed\n", file=base::get(".ExTimings", pos = 'CheckExEnv'))
base::assign(".format_ptime",
+ function(x) {
+   if(!is.na(x[4L])) x[1L] <- x[1L] + x[4L]
+   if(!is.na(x[5L])) x[2L] <- x[2L] + x[5L]
+   options(OutDec = '.')
+   format(x[1L:3L], digits = 7L)
+ },
+ pos = 'CheckExEnv')

### * </HEADER>

...

base::assign(".dptime", (proc.time() - get(".ptime", pos = "CheckExEnv")), pos = "CheckExEnv")
base::cat("data_name", base::get(".format_ptime", pos = 'CheckExEnv')(get(".dptime", pos = "CheckExEnv")), "\n", file=base::get(".ExTimings", pos = 'CheckExEnv'), append=TRUE, sep="\t")

...

base::assign(".ptime", proc.time(), pos = "CheckExEnv")

Consequently when the file generated by devtool's check is used as reference output, a lot of differences are found.

I use devtools 1.13.4 (2017-11-09 CRAN (R 3.4.2)).

Here are some examples from the wild:

This behavior is likely changed in devel devtools, which uses the rcmdcheck package to run R CMD check. If it is not fixed I would encourage you to open this issue in that repository.

Yes, still present. Raised an issue for rcmdcheck.

So, this is actually a devtools issue, because devtools always uses --timings, so maybe it needs an argument to make this optional?

devtools/R/check.r

Line 169 in dbac1fa

args <- c("--timings", args)

[jimhester]

Seems like we should hoist the "--timings" to the default for args, so you can turn it off if desired.

[gaborcsardi]

Yeah, that's good, too.

[jimhester]

Ok if you check with devtools::check(args = NULL) this should now turn off the timings.

[gaborcsardi]

And you also need cran = FALSE, because --as-cran also turns on the timings.
