The discussion on R-pkg-devel has been about how to fix default
download.file behaviour that has previously worked on all platforms, and
is now broken by a very recent change at the St Louis Fed. A method
working a few days ago would not be a guarantee that it still works.
Before people go overboard changing their workflow, let me point out
that this can likely be fixed by a user setting
options(download.file.method="libcurl")
or
options(download.file.method="wget")
or
options(download.file.method="wininet")
See ?download.file for more options, which will be platform specific
(but maybe not as specific as using an excel macro).
The package developer problem is slightly different. That problem, the
problem that Joshua is working on, is that the default method no longer
works. So either the default method has to be fixed or users need to be
directed to some solution that will depend on their platform.

As a suggestion ( although not that efficient ) there is an excel macro
that can download the information. I'm not sure if you're aware of it or
not but just thought I'd mention it just in case.

Hi,
I have started getting an error when using getSymbols for FRED in
quantmod. It was working fine a few weeks ago. I'm using R on a Mac:
getSymbols("CPIAUCSL", src="FRED")Error in download.file(paste(FRED.URL,
"/", Symbols[[i]], "/", "downloaddata/", : cannot open URL '
http://research.stlouisfed.org/fred2/series/CPIAUCSL/downloaddata/CPIAUCSL.csv
'
If I paste the URL in the error message into a browser it downloads the
csv fine, so I think the url is ok.It also works ok for other sources, such
as yahoo etc.
The FRED http:// URLs now redirect to https://. That causes issues
with the default method for download.file on some platforms. I'm
aware of the issue and working on a fix.
See the conversation on R-package-devel if you're interested in the
details:

Any insights would be appreciated.
Thanks,Alex
