optparse_parameters: optparse_parameters - parse easily the command line parameters

Description

This function is made to be used with the functions optparse_flag, optparse_numeric, optparse_integer, optparse_character and/or optparse_list

optparse_parameters parses arguments based on its parameters.

You just have to call optparse_parameters with named arguments. Each parameter is the result of either optparse_flag, optparse_numeric, optparse_integer, optparse_character or optparse_list

Usage

optparse_parameters(
  fix_hyphens = TRUE,
  fix_dots = TRUE,
  add_trailing_hyphens = TRUE,
  args = NULL,
  no_optparse = FALSE,
  ...
)

Arguments

fix_hyphens

logical - whether to turn underscores into hyphens or not

fix_dots

logical - whether to turn points into hyphens or not
