ct_get_ref_table | R Documentation |
The first time, the function will read from disk, the second time from the
environment. In the case of a necessary update the new data will be saved
to the environment for the current session.
You can use this table to look at the reference tables and if necessary
extract respective classification codes by hand. In general we would
recommend the function ct_commodity_lookup
for this purpose.
It uses the present function in the backend.
ct_get_ref_table(dataset_id, update = FALSE, verbose = FALSE)
dataset_id |
The dataset ID, which is either partner, reporter or a valid classification scheme. |
update |
If TRUE, downloads possibly updated reference tables from the UN. Default: FALSE. |
verbose |
If TRUE, sends status updates to the console. If FALSE, runs functions quietly. Default: FALSE. |
The function allows you to query most possible input parameters that are listed by the Comtrade API. The following dataset_ids are permitted:
Datasets that contain codes for the commodity_code
argument. The name is
the same as you would provide under commodity_classification
.
'HS' This is probably the most common classification for goods.
'B4'
'B5'
'EB02'
'EB10'
'EB10S'
'EB'
'S1'
'S2'
'S3'
'S4'
'SS'
'reporter'
'partner'
'mode_of_transport'
'customs_code'
'flow_direction'
