A sample of the UN Comtrade Database prepared by the United Nations Department of Statistics with official international trade information.
Value
a dataframe object contains the five variables passed as parameters to the get_zerotradeflow() function (year, exporter, importer, item, trade) including the bilateral trade flow equal to zero.
Details
In the following example the original base (comtrade.rda) has only 229,585 information on positive bilateral trade flow (greater than zero). However, after expanding this base to also present the bilateral trade flow equal to zero, the new base will have 1,255,892 observations (both positive and zero flow). Note that the final size of the base will depend on the number of years, the number of exporting and importing countries and the items present in the base. Since the distinct number of exporting and importing countries has an important determining factor in the expansion of the base (see the examples with the distinct.rda and same.rda bases).
A dataset consisting of two years, 24 exporting countries, 24 importing countries, 1,241 Harmonized System codes and the value of exports in dollars. The data includes the following fields:
* ano - Numeric. Year in which exports were carried out
* ido - String. ISO code corresponding to the exporting country
* idd - String. ISO code corresponding to the importing country
* HS4 - Numeric. HS4 code corresponding to the merchandise sold
* comercio - Numeric. Dollar value of exports
Examples
# \donttest{
zeroflow <- get_zerotradeflow(comtrade, ano, ido, idd, HS4, comercio)
