Changes in version 0.0.2 (2024-01-24)                  

new features

  - download_kospi_master() and get_kospi_master_dataframe() functions
    are added. if you execute these two functions sequentially, you can
    obtain the KOSPI master data frame. and it contains a lot of
    informations. get_kospi_master() function combines these two
    functions.

  - download_kosdaq_master() and get_kosdaq_master_dataframe() functions
    are same as above. get_kosdaq_master() function combines these two
    functions.

  - kospi_master_columns and kosdaq_master_columns datasets contain
    English and Korean column names.

  - get_current_index() function is added. the index_code argument can
    be (KOSPI: "0001", KOSDAQ: "1001", KOSPI200: "2001")

bug fixes

  - modified typo .Reviron -> .Renviron and added
    usethis::edit_r_environ() for the environment variable checking
    error messages.

bug fixes

  - A return value typo error of print_trading_env() function (livr ->
    live) is modified.

  - inherits(orders, "data.frame") condition is added to
    kis_cancel_all() function, because the get_orders() function inside
    of kis_cancel_all() function returns a list of error code if the
    class of return value is not a data.frame. So if get_orders()
    function returns a list of error code, the print_trading_env()
    function returns the same list of error code.
