Collect every FOMC policy statement (the Federal Open Market Committee's statement on its policy decision, issued after a scheduled meeting or an unscheduled call) from January 2006 to the latest one, from the Federal Reserve's website.

Start from the meeting calendar at https://www.federalreserve.gov/monetarypolicy/fomccalendars.htm (2021 onward) and the one page per year at https://www.federalreserve.gov/monetarypolicy/fomchistoricalYYYY.htm for 2006 to 2020.

Rules: send a user agent that identifies the request as "AEM 6850 class demo; <address>"; at most one request per second; save every page you fetch in cache/ and never fetch the same page twice; if the server answers 429, wait and retry.

Write fomc_statements.csv with one row per statement and the columns date (YYYY-MM-DD), url (the address after redirects), words, text (the statement's paragraphs only), scheduled (TRUE after a scheduled meeting, FALSE after an unscheduled call). Use R. Print the number of statements per year when you are done.
