Description

A function to calculate the percentage change on world imports and exports

Usage

1
2
changeflowmessage(dtf0, dtf1, import = "Import", export = "Export",
  variable = "quantity")

Arguments

dtf0

a data frame of trade flows before the modification

dtf1

a data frame of modified trade flows

import

code indicating import data, can be "Import" for Comtrade and 1 for Comext

export

code indicating export data, can be "Export" for Comtrade and 2 for Comext

Note: Add a function changeflowmessage(dtf, dtfsplit) which will return a character string about both trade flows. This function could be defined in the main scope and reused in other parts of the workflow. Or maybe not because the quantity is not empty for addpartner flow and shaveprice.
