These functions allow for a consistent framework of options for the
crunch package. When retrieving options, envOrOption() first
looks for options set with the set_crunch_opts(), followed by
options in the environment (see Sys.getenv())
and finally in the R options (see options).
envOrOption(opt, default = NULL, expect_lgl = FALSE, expect_num = FALSE)
set_crunch_opts(..., .source = NULL)the option to get/set
if the specified option is not set in either the option or as an environment variable, use this instead.
Named arguments describing which options to set
(Optional) A character vector describing where the option was set from
the value of the option
Environment variables are generally set at the operating system level,
but R does look at a file called .Renviron on startup, and you can
also set them using the function Sys.setenv(). Options are generally
set using a options() function in the .Rprofile file, but can be
set using that function anywhere.
The main crunch R package uses the following options (note that
the option name is in all capital letters, with "." replaced with
"" and a "R" prefix when used as an environment variable):
| Option name | Env variable | Default value | Explanation |
| crunch.api | R_CRUNCH_API | "https://app.crunch.io/api/" | URL of API to use |
