help with EXPASY HTML form submission in RCurl package
Hi,
I am trying to submit a form to the EXPASY protscale server (
http://www.expasy.ch/tools/protscale.html). I am using the RCurl package and
the postForm function available in it. I have extracted the variables for
the form from the HTML source page. According to the syntax of postForm, I
just need to mention the url and assign values to the input mentioned in the
HTML code.
The code that I am using is:

RCurl and cookies in POST requests
Hello.
I know that it's usually possible to write cookies to a cookie
file by removing the curl handle and doing a gc() call. I can do
this with getURL(), but I just can't obtain the same results with
postForm().
If I use:
curlHandle <- getCurlHandle(cookiefile=FILE, cookiejar=FILE)
and then do:
getURL(http://example.com/script.cgi, curl=curlHandle)
rm(curlHandle)
gc()
it's OK, the cookie is there. But, if I do (same handle; the
parameter is a dummy):
postForm(site, .params=list(par="co...

RCurl::postForm() -- how does one determine what the names are of each form element in an online html form?
Dear R-Help,
I am looking into using the Open Calais web service (http://
sws.clearforest.com/calaisViewer/) for text mining purposes. I would
like to use R to post text into one of the forms on their website.
In package RCurl, there is a function called postForm(). This sounds
like it would do the job. Unfortunately the URL used in the example is
no longer valid (i have emailed the maintainer about this).
Question: How does one determine the name of the form elements to use?
is there an R function which will print out the names of these
elements perhaps?...

RCurl and postForm()
Hi everybody,
I think that I am missing something fundamental in how strings are passed from a postForm() call in R to the curl or libcurl functions underneath. For example, I can do the following using curl from the command line:
$ curl -d "Archbishop Huxley" "http://www.datasciencetoolkit.org/text2people"

scraping with session cookies
...e some data from the web.
The problem that I am having is that I cannot get passed the disclaimer
page (which produces a session cookie). I have been able to collect some
ideas and combine them in the code below but I dont get passed the
disclaimer page.
I am trying to agree the disclaimer with the postForm and write the cookie
to a file, but I cannot do it succesfully....
The webpage cookies are written to the file but the value is FALSE... So
any ideas of what I should do or what I am doing wrong with?

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.

Downloading tab separated data from internet
Hi all,
I am trying to download some tab separated data from the internet. The data
is not available directly at the URL that could be known apriori. There is
an intermediate form where start and end dates have to be given to get to
the required page.
For example, I want to download data for a station 03015795. The form for

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
