get_exchangerate_from_interval(table, currency_code, from, to)

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.
• from: start day of the interval.
• to: end day of the interval.

Returns

Details

As exchange rates are not published on the weekends fetching values from an interval containing a weekend will result in a response that omits those days.

Examples

tryCatch(
  {
    ## Fetch the exchange rate table from the past week
    response <- get_exchangerate_tables_from_interval("A", Sys.Date() - 7, Sys.Date())
    ## Preview response content
    response$content
  },
