In stix-global/eutradeflows: Download bilateral trade flow data from Eurostat Comext

Description

Parse a table of Combined Nomenclature Code changes obtained from EUROSTAT Ramon. The two functions subsequent_codes and previous_codes look for all the subsequent (or previous) codes of a given product code. They return a table with dates for each code transition. the function subsequent_and_previous_codes binds the two tables above to provide all ancestor codes and a descendant codes.

vector_of_subsequent_and_previous_codes Creates a vector of unique codes.

Usage

subsequent_codes(
  orig_codes_to_check,
  code_changes_table = eutradeflows::cn_code_changes
)

previous_codes(
  dest_codes_to_check,
  code_changes_table = eutradeflows::cn_code_changes
)

subsequent_and_previous_codes(
  codes_to_check,
  code_changes_table = eutradeflows::cn_code_changes
)

vector_of_subsequent_and_previous_codes(
  codes_to_check,
  code_changes_table = eutradeflows::cn_code_changes
)

Arguments

orig_codes_to_check	character product code(s)
code_changes_table	a table of code changes, defaults to cn_code_changes (already contained in the package)
dest_codes_to_check	character product code(s)
codes_to_check	character product code(s)

Value

data frame of all subsequent codes for the given original code

origin_code destination_code orig_end_year dest_start_year <chr> <chr> <dbl> <dbl> 44072969 44072799 2006 2007

vector of codes

Examples

subsequent_codes("44072969")
previous_codes("44072969")
