Usage: R CMD $name [options] pkgdirs
Check R packages from package sources in the directories specified by
pkgdirs. A variety of diagnostic checks on directory structure, index
and control files are performed. The package is installed into the log
directory (which includes the translation of all Rd files into several
formats), and the Rd files are tested by LaTeX (if available). All
examples and tests provided by the package are tested to see if they run
successfully.
Options:
-h, --help print short help message and exit
-v, --version print version info and exit
-l, --library=LIB library directory used for test installation
of packages (default is outdir)
-o, --outdir=DIR directory used for logfiles, R output, etc.
(default is 'pkg.Rcheck' in current directory,
where 'pkg' is the name of the package checked)
--no-clean do not clean outdir before using it
--no-codoc do not check for code/documentation mismatches
--no-examples do not run the examples in the Rd files
--no-install skip installation and associated tests
--no-tests do not run code in tests subdirectory
--no-vignettes do not check vignettes in Sweave format
--no-latex do not run LaTeX on help files
--use-gct use 'gctorture(TRUE)' when running examples/tests
By default, all test sections are turned on.
