Below are the R options and environment variables that are used by the
futurize package and packages enhancing it.
WARNING: Note that the names and the default values of these options may
change in future versions of the package. Please use with care until
further notice.
Packages must not change future options
Just like for other R options, as a package developer you must not change
any of the below futurize.* options. Only the end-user should set these.
If you find yourself having to tweak one of the options, make sure to
undo your changes immediately afterward.
Options for debugging
- futurize.debug:
(logical) If
TRUE, extensive debug messages are generated. (Default:FALSE)
Environment variables that set R options
All of the above R futurize.* options can be set by corresponding
environment variable R_FUTURIZE_* when the futurize package is
loaded. This means that those environment variables must be set before
the futurize package is loaded in order to have an effect.
For example, if R_FUTURIZE_DEBUG=true, then option
futurize.debug is set to TRUE (logical).
