RCurl: using netrc with curlPerform
Hello,
I am having trouble getting the curlPerform function to authenticate
using the .netrc file. From the documentation I've read it
certainly seems as though this function should be able to authenticate
via the .netrc file.
The example I am using here comes from the "R as a Web Client- the RCurl
package" paper and demonstrates using the .netrc file to access the

RCurl - curlPerform - Time out?!?
Hi,
I am working with the RCurl package and I am using the curlPerform
function for an soap-query.
The problem is that the code is usually working well, but sometimes the
connection gets lost.
So I wrote a while-loop to repeat the query if anything might happened
so that the same query runs again, but if the query-faults it takes a
very long time for the repetition.
My question is if there

All,
I''m missing something simple, I think. I am writing a spec to say that my

Removing Embedded Null characters from text/html
Hi,
I'm trying to download some data from the web and am running into
problems with 'embedded null' characters. These seem to indicate to R
that it should stop processing the page so I'd like to remove them.
I've been looking around and can't seem to identify exactly what the
character is and consequently how to remove it.

counter_cache, has_many and belongs_to
I am a bit confused about counter_cache here. The API docs
http://api.rubyonrails.org/classes/ActiveRecord/Associations/ClassMethods.html
say that only the belongs_to association can take the :counter_cache
option. When I try to use it on a has_many I get an "unknown key(s):
counter_cache" error.
Why would this be the case? belongs_to means that this model has a
