get_exchangerate_table_from function

Retrieves the exchange rate table from a specific date.

get_exchangerate_table_from(table, date)

Arguments

• table: specifies which table should be fetched.
• date: date from which the exchange rate table should be fetched.

Returns

nbp_api_response object containing the exchange rate table from the specified date.

Details

As exchange rate tables 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 A exchange rate table from a week ago
    response <- get_exchangerate_table_from("A", Sys.Date() - 7)
    ## Preview response content
    response$content
  },

)
