One of the most frustrating parts of R CMD check is getting all of your examples to pass - whenever one fails you need to fix the problem and then restart the whole process. This function makes it a little easier by making it possible to run all examples from an R function.

  pkg = ".",
  start = NULL,
  show = TRUE,
  test = FALSE,
  run = FALSE,
  fresh = FALSE,
  document = TRUE



The package to use, can be a file path to the package or a package object. See as.package() for more information.


Where to start running the examples: this can either be the name of Rd file to start with (with or without extensions), or a topic name. If omitted, will start with the (lexicographically) first file. This is useful if you have a lot of examples and don't want to rerun them every time you fix a problem.




if TRUE, code in \donttest{} will be commented out. If FALSE, code in \testonly{} will be commented out.


if FALSE, code in \dontrun{} will be commented out.


if TRUE, will be run in a fresh R session. This has the advantage that there's no way the examples can depend on anything in the current session, but interactive code (like browser()) won't work.


if TRUE, document() will be run to ensure examples are updated before running them.
