[R] File Downloading Problem

[Santosh Srinivas]

Nope Duncan ... no changes .. the same old way without a proxy ... actually
the download.file is being returned "403 forbidden" which is strange.

These are just two lines that I am trying to run.

sURL<-
"http://www.nseindia.com/content/historical/EQUITIES/2010/NOV/cm01NOV2010bha
v.csv.zip"
download.file(sURL,"test.zip")

Put the same URL in a browser and it works fine.

Are you using a proxy?  If you've recently updated R, you may have told 
it not to use the proxy.  You can test this by running

setInternet2(TRUE)

(which will use a proxy if one is defined in Internet Explorer) and 
repeating the download.file() call.  You can make Internet2 the default 
by putting --internet2 on the command line when you start R.
