Yes, you're right, I was wrong. I've been trying to use the postForm
method in RCurl but it doesn't work. I'll check the source code in
this package to see if I can improve it.

Thanks for your interest, Paul.
I've checked the source code of TSjson and I've seen that what it does
is to call a Python script to retrieve the data. In fact, I've already
done this with Java using the URLConnection class and sending the
requested values to fill the form.
However, I think it
I'd like to make you note that I've discovered that package RCurl
already provides a utility that allows interaction via POST requests
with servers. In fact, the FAQ for RCurl contains specifically an
example with an aspx page:
x = postForm(http://www.fas.usda.gov/psdonline/psdResult.aspx;,
I must be really dense, I know RCurl provides a POST capability, but I
don't see how this allows interaction. Suppose the example actually
worked, which it does not. (Unfortunately many of the examples in RCurl
seem to be marked \dontrun{} or disabled with some if() condition.) When
you post
Hi. I'm trying to write an application to retrieve financial data
(specially bonds data) from FINRA. The web page is served dynamically
from an asp.net application:

I'd like to know if it's possible to fill dynamically
Hi Jose,
I think this is more of an r-help question so I'm going to forward
your question there: R-devel is really for the development of R
itself, not development with R.
Cheers,

Er, no!
R help is (mainly) for helping beginners. We usually
I don't know of an easy way to do this in R. I've been doing something
similar with python scripts called from R. If anyone knows how to do
this with just R, I would appreciate hearing too.

I think RHTMLForms works if you have a single form, but I have not been
able to see how to use it when you need to go through a sequence of
dynamically generated forms (like you can do with Python mechanize).

As far as getting to the data, I think the best way to do this sort of
thing would be if the site supports a SOAP or REST interface. When they
don't (yet) then one is faced with clicking through some pages. Python
or Java is one way to automate the process of clicking through the
pages.
