zerotradeflow is a system for creating the bilateral
trade flow between a country pair equal to zero. You provide the data,
tell zerotradeflow which variables are of interest and it
expands the base by creating the bilateral zero trade flow. The bases on
the flow of trade between countries only report positive trade (greater
than zero), however, for some analyzes of gravitacional models, data on
zero flow is also necessary.
To install the package, one of the two standard methods
for installing packages in R can be adopted. Directly
through the cran
(choosing the closest repository):
install.packages ("zerotradeflow")Or the development version from GitHub:
# install.packages ("devtools")
devtools::install_github ("AlexandreLoures/zerotradeflow")In the latter case, the latest version of the package
will be installed.
The operation of the zerotradeflow package consists of
informing where the data are (the base) to be expanded and indicating
the variables: year, exporting country, importing country, Harmonized
Commodity Designation and Coding System (or other classification) and
value of exports/imports. It takes into account that the order must be
obeyed: data, year, exporter, importer, designation and coding and flow
value.
