get_zerotradeflow.RdCreates zero bilateral trade flow for a given pair of countries.
Arguments
- data
a data set containing the variables that will be used to guide the expansion of the base including all possible combinations of the reference variables.
- year
refers to the column in the database that contains information for the years under review.
- exporter
refers to the column with the ISO codes (ISO 3166 standard - Codes for the representation of names of countries and their subdivisions, created and maintains by International Organization for Standardization - ISO) of each exporter country (Ex.: BRA, PRT, ITA, USA,...).

- trade
refers to the column in the database that contains information about the value of exports/imports
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
The zerotradeflow package allows generating the bilateral trade flow equal to zero of each country pair in each year present in the database passed in data parameter. Since, by default, data on bilateral trade flows of countries only report positive trade flows (flows greater than zero).
Function to expand the database with the bilateral trade flow equal to zero, passing the following parameters:
