From R 3.2.0, check:

TRUE
TRUE means R was built such that HTTPS is supported. If you see
FALSE, make sure libcurl is available when/if you build R from source.
I do have TRUE for this. The default behaviour still does not work.

I think the St Louis Fed has moved to using https for connections, and I
believe all the US government web sites are doing this. An http request is
automatically switched to https. The default download.file method does not
seem to handle this, but method="wget" does:
tmp <- tempfile()
download.file("http://research.stlouisfed.org/fred2/series/M2/downloaddata/M2.csv",
destfile = tmp)
