RGoogleDocs stopped working
Hello,
Some code using RGoogleDocs, which had been working smoothly since the
summer, just stopped working. I know that it worked on November 3rd, but it
doesn't work today. I've confirmed that the login and password still work
when I log in manually. I've confirmed that the URL gives the same error
when I paste it into Firefox. I don't know enough about this web service to

RCurl : limit of downloaded Urls ?
Dear Rexperts,
I am using R to query google.
I am getting different results (in size) for manual queries and queries sent
through "getForm" of RCurl.
It seems that RCurl limits the size of the text retrieved (the maximum I
could get is around 32 k bits).
Any idea how to get around this ?
Thanks in advance

RCurl compilation error on ubuntu hardy
Dear list members,
I encountered this problem and the solution pointed out in a previous
thread did not work for me.
(e.g. install.packages("RCurl", repos = "http://www.omegahat.org/R")
I work with Ubuntu Hardy, and installed R 2.6.2 via apt-get.
I really need RCurl in order to use biomaRt ... any help would be
greatly appreciated.
Best wishes,

Scraping a web page.
Folks,
I want to scrape a series of web-page sources for strings like the following:
"/en/Ships/A-8605507.html"
"/en/Ships/Aalborg-8122830.html"
which appear in an href inside an <a> tag inside a <div> tag inside a table.
In fact all I want is the (exactly) 7-digit number before ".html".
The good news is that as far as I can tell the the <a>

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: authentication when posting forms
Hi,
Has anyone successfully used RCurl for posting data to a
password-protected site? I
have tired using option netrc=1 with both postForm and curlPerform (with
postfields option) but can't authenticate.
I would happily provide more details if some one has had some experience
with this.
Thanks very much.

[BioC] Rcurl 0.8-1 update for bioconductor 2.7
Hi Patrick,
Greetings from !(sunny) Pittsburgh.
What's the scoop on RCurl on windows (XP)?
I've tried to install RCurl_0.92-0.zip and RCurl_0.9-3.zip,
with both R 2.7.2 and R 2.8.0 from the RGUI (utils:::menuInstallLocal),
and get the error
"Windows binary packages in zipfiles are not supported".
which (according to google's one and only hit) comes from a perl script.

changing 'https' to 'http' when using download.file(), any side effects or just use RCurl?
Dear R-Help,
>From reading the help file, it is my understanding the the download.file()
function does not support HTTPS connections. So therefore, understandably,
the follow produces an error:

I am trying to solve a problem but with no success for the past 4 days.
I use the RCurl package with R 2.8.1, and when I try to use the function
FTPUpload, it uploads the file but does not stop.
It repeats the content of the file without stopping and the destination file
keeps getting bigger and bigger.

is there a way to extract fata from web pages through some R function ?
I deal with a huge amount of Biology data stored in different databases.
The databases belongig to Bioconductor organization can be accessed through Bioconductor packages.
Unluckily some useful data is stored in databases like, for instance, miRDB, miRecords, etc ... which offer just an
interactive HTML interface. See for instance

How to set cookies in RCurl
Hi,
I am trying to access a website and read its content. The website is a
restricted access website that I access through a proxy server (which
therefore requires me to enable cookies). I have problems in allowing Rcurl
to receive and send cookies.
The following lines give me:

RCurl and Google Scholar's EndNote references
Hi!
I've performed a Google Scholar Search using a query, let's say "Frank
Harrell", and parsed the links to the EndNote references from the resulting
HTML code. Now I'd like to download all the references automatically. For
this, I have tried to use RCurl, but I can't seem to get it working: I
always get error code "403 Forbidden" from the web server.

When I try to install tweetR on Ubuntu, I get the error message below. It is

xyplot: superpose 2 time series with different time intervals
I could use some advice regarding xyplot.
I've got 2 time series. Both cover approximately the same period of
time (ie, 1940 to 2009). But one series has annual data and the other
has monthly data. One refers to university enrollment; the other to
unemployment rates. Both are currently in the same data frame.
I'd like to use the monthly times series as a light grayscale
