get_exchangerate_from function

Retrieves the exchange rate from a specific date.

get_exchangerate_from(table, currency_code, date)

Arguments

• table: specifies which from which table the exchange rate should be fetched.
• currency_code: code of the currency for which the exchange rate should be fetched.
• date: date from which the exchange rate should be fetched.

Returns

nbp_api_response object containing the exchange rate from the specified date.

Details

As exchange rates are not published on the weekends fetching values from a weekend date will result in a 404 error. In those cases the function returns an error with an appropriate message.

Examples

tryCatch(
  {
    ## Fetch the euro exchange rate from a week ago
    response <- get_exchangerate_from("A", "EUR", Sys.Date() - 7)
    ## Preview response content
    response$content
  },
  error = function(e) message(e)
)
