postcard Options

Internally used, package-specific options. All options will prioritize R options() values, and fall back to environment variables if undefined. If neither the option nor the environment variable is set, a default value is used.

Arguments

verbose

numeric verbosity level. Higher values means more information is printed in console. A value of 0 means nothing is printed to console during execution (Defaults to 2, overwritable using option 'postcard.verbose' or environment variable 'R_POSTCARD_VERBOSE')

Checking Option Values

Option values specific to postcard can be accessed by passing the package name to env.
