release_package_to_CRAN.R

# check out all info here: https://r-pkgs.org/release.html

# update NEWS
# udpate cran-comments.Rd

tools::resaveRdaFiles("data/")

# build the tarball and check whether the size is below 5 MB
devtools::build()

devtools::release_checks()

devtools::check_win_devel() # this will just send to server, then it is useable again

devtools::check_rhub() # this sends to server but follows the progress, so the session is not useable in the meantime

# in a new session start:
devtools::check(args = "--as-cran")

devtools::spell_check()

devtools::release()

# or when you don't want all tests: 
# devtools::release(check = FALSE)
