isCRANcheck
tries to identify if one is running CRAN-like checks.
isCRANcheck(...)
isCHECK()

each argument specifies a set of tests to do using an AND operator. The final result tests if any of the test set is true. Possible values are:
|
Currently isCRANcheck
returns TRUE
if the check is run with
either environment variable _R_CHECK_TIMINGS_
(as set by flag '--timings'
)
or _R_CHECK_CRAN_INCOMINGS_
(as set by flag '--as-cran'
).
Warning: the checks performed on CRAN check machines are on purpose not always run with such flags, so that users cannot effectively "trick" the checks. As a result, there is no guarantee this function effectively identifies such checks. If really needed for honest reasons, CRAN recommends users rely on custom dedicated environment variables to enable specific tests or examples.
isCHECK
: tries harder to test if running under R CMD check
.
It will definitely identifies check runs for:
unit tests that use the unified unit test framework defined by pkgmaker (see utest
);
examples that are run with option R_CHECK_RUNNING_EXAMPLES_ = TRUE
,
which is automatically set for man pages generated with a fork of roxygen2 (see References).
Currently, isCHECK
checks both CRAN expected flags, the value of environment variable
_R_CHECK_RUNNING_UTESTS_
, and the value of option R_CHECK_RUNNING_EXAMPLES_
.
It will return TRUE
if any of these environment variables is set to
anything not equivalent to FALSE
, or if the option is TRUE
.
For example, the function utest
sets it to the name of the package
being checked (_R_CHECK_RUNNING_UTESTS_=<pkgname>
),
but unit tests run as part of unit tests vignettes are run with
_R_CHECK_RUNNING_UTESTS_=FALSE
, so that all tests are run and reported when
generating them.
