getopt 1.20.3

• Now by default getopt won’t override a user specified opt argument if argv is in the global environment. Will continue to use argv as a default for opt if it is in the global environment and the user does not specify an opt argument (for littler compatibility).

getopt 1.20.2

• Now allows one to pass an empty string to a character option. Thanks Matthew Flickinger for bug report.

getopt 1.20.1

• Now explicitly imports the na.omit method from the stats package. Thanks Derrick Oswald for bug report.
• Improved parsing for negative numbers preceded by a space instead of a ‘=’ sign.
  Thanks Roman Zenka for improved regular expression.
• Slightly more informative error message if storage.mode coercion results in an NA. Thanks Roman Zenka for suggestion.

getopt 1.20.0

• Type of “numeric” in spec automatically cast to “double”.
  Previously users might have had an error passing negative numbers if they accidentally specified “numeric” instead of “double”.
• Project website moved to https://github.com/trevorld/getopt
• Exports new function sort_list.

getopt 1.19.1

• If a passed in option matches multiple options in the getopt specification but matches one exactly then getopt now uses that value instead of throwing a “long flag is ambiguous” error.

getopt 1.19.0

• Exports new function get_Rscript_filename that returns name of calling script, getopt now uses this function value as default for command argument
• Documentation improved and now highlights differences between getopt and optparse packages for new undecided users
