Hello, this is actually expected behavior. The Comtrade DB does not include EU-28
as a partner country, only as a reporter country. Check it out:
comtradr::ct_country_lookup("EU-28", type = "partner")
#> [1] "No matching results found"
The func ct_country_lookup()
uses regex for semi-fuzzy look ups, so we can see all of the partner countries that contain the string eu
:
comtradr::ct_country_lookup("EU", type = "partner")
#> [1] "Africa CAMEU region, nes" "Eastern Europe, nes" "Europe EFTA, nes" "Europe EU, nes" "Neutral Zone"
#> [6] "Other Europe, nes"
And we can see that EU-28
is a valid reporter country:
comtradr::ct_country_lookup("EU", type = "reporter")
#> [1] "EU-28"
Because of this issue, I'm working on updates to the error message returned when a bad country string is passed in. I should be pushing these edits this weekend. So now the output looks like this:
df <- ct_search(reporters = "USA",
partners = c("China",
"EU-28",
"Rep. of Korea"),
trade_direction = "exports")
#> Error: From arg 'partners', these values were not found in the country database: EU-28
Thanks for this great package! I have an issue with looking for EU trade statistics. Every time I look for the EU I get the same error massage. I suspect this may be related to the special character in the string.
df <- ct_search(reporters = "USA", partners = c("China", "EU-28", "Rep. of Korea" ), trade_direction = "exports")
Error: Result 2 must be a single string, not a character vector of length 0 Run
