Description

Accesses api.tradestatistics.io and performs different API calls to transform and return tidy data.

Usage

ots_create_tidy_data(
  years = 2020,
  reporters = "all",
  partners = "all",
  commodities = "all",
  sections = "all",
  table = "yr",
  max_attempts = 5,
  use_cache = FALSE,
  file = NULL
)

Value

A tibble that describes bilateral trade metrics (imports, exports, trade balance and relevant metrics such as exports growth w/r to last year) between a reporter

and partner country.

Arguments

years

Year contained within the years specified in api.tradestatistics.io/year_range (e.g. c(2002,2004), c(2002:2004) or 2002). Default set to 2019.

reporters

ISO code for reporter country (e.g. "chl", "Chile" or c("chl", "Peru")). Default set to "all".

sections

HS section codes (e.g. "01"). Default set to "all".

table

Character string to select the table to obtain the data. Default set to yr (Year - Reporter). Run ots_tables in case of doubt.

max_attempts

How many times to try to download data in case the API or the internet connection fails when obtaining data. Default set to 5.

use_cache
