  <h1>The RCurl Package</h1>
  <p align="right">
   <a href="RCurl_1.96-0.tar.gz">RCurl_1.96-0.tar.gz</a>
   (20 June 2014)
  </p>
  <p align="right">
   <a href="philosophy.html">Manual</a>
  </p>
  The RCurl package is an R-interface to the
  <a href="http://curl.haxx.se">libcurl</a>
  library that provides HTTP facilities. This
allows us to download files from Web servers, post forms, use HTTPS
(the secure HTTP), use persistent connections, upload files, use
binary content, handle redirects, password authentication,  etc.
  <p>The primary top-level entry points are</p>
  <ul>
   <li>
    <a href="installed/RCurl/html/getURL.html">getURL()</a>
   </li>
   <li>
    <a href="installed/RCurl/html/getURL.html">getURLContent()</a>
   </li>
   <li>
    <a href="installed/RCurl/html/postForm.html">getForm()</a>
   </li>
   <li>
    <a href="installed/RCurl/html/postForm.html">postForm()</a>
   </li>
  </ul>
  However, access to the C-level routines is also available
via the R code, and one can specify options to all of the
libcurl operations to control how they are performed.
Documentation about the options and commands
can be found at the
  <a href="http://curl.haxx.se">libcurl web site</a>
  <p>
   R functions can be specified to collect text from both the
response and its headers. This can be used to customize the processing
of the requests and feed the results to higher-level processing
(e.g. HTML parsing via the htmlTreeParse function in the
   <a href="http://www.omegahat.org/RSXML">XML package</a>
   ).
  </p>
  <p>
   This package will be used to implement the low-level communication
in the
   <a href="http://www.omegahat.org/SSOAP">SSOAP</a>
   package
and other high-level packages that utilize HTTP to exchange
requests and data.

    <a href="http://cran.r-project.org/src/contrib/Descriptions/httpRequest.html">httpRequest</a>
   </dt>
   <dd>The httpRequest is a package on CRAN that implements a small
      part of HTTP directly in R using sockets.</dd>
   <dt>httpClient</dt>
   <dd>
    I have developed the
    <b>httpClient</b>
    package using
      R code and connections that supports additional
      aspects of R and HTTP, such as cookies, character escaping, and also
      SSL for HTTPS. I haven&apos;t released the code (favoring the
      approach of building on existing C code) but can make it available if anyone
      is interested.
   </dd>
  </dl>
  While having code in R makes it easier to understand, explore and
modify, it is probably better to use existing specialized libraries
like libcurl rather than doing this ourself.  We gain speed and a
large development community that cares about getting things right and
testing them.
We will explore the use of
  <a href="http://www.w3.org/Library">libwww</a>
  <h2>Issues</h2>
  Using the opaque data structures of the libcurl infrastructure
means that we cannot easily access the file descriptors used
in the communication. This  makes it somewhat more difficult
to integrate these streams into  an R even loop
(e.g.
  <a href="http://www.omegahat.org/REventLoop">REventLoop</a>
  ).
We can potentially turn them into regular connections
(if the internal API is made &quot;public&quot;).
  <h2>License</h2>
  This is distributed under the
  <a href="http://www.omegahat.org/BSDLicense.html">BSD license</a>
  in the same spirit as libcurl itself.

Investigating such questions is part of what we\nwant to do.\n\n<h2><a name=toc3>Policy</a></h2>\n<p>\nSpecific goals and procedures are still being developed, but the current\npolicy includes the following.\n<ul>\n<li>The code developed will be created and offered as open-source\nsoftware, under a <a href=\"License.html\">public license</a> similar to the licenses used for\nLinux, Netscape, and R.\n<li>Contributions are encouraged in the form of software compatible\nwith the three-level structure shown above.  This includes but is not restricted\nto: Java packages; software in other languages, if it can be structured as a module\ndefined in CORBA;  software for the interactive languages built in\nOmega.\n<li>We anticipate organizing software into layers, including at\nleast two:  a general contributed software layer and a central layer for\ncore Omega facilities.\n<li>We have established a number of\n<a href=\"http://www.omegahat.net/mailman/listinfo/\">mailing\nlists</a> for exchange of ideas.  These include lists for general\ndiscussion, for Omega packages, for interactive languages using\nOmega, and for technical issues about Omega itself.\n</ul>\n<p>\n<h2><a name=toc4>Membership</a></h2>\n<p>\nThe current core group of Omega developers includes:\n<center>\n<table border=\"1\">\n<tr>\n<th align=left><font size=-1><a href=\"http://www.stat.wisc.edu/~bates/\">Douglas Bates</a></font></th>\n<th align=left><font size=-1><a href=\"http://cm.bell-labs.com/stat/jmc/\">John Chambers</a></font> </th>\n<th align=left><font size=-1><a href=\"http://www.public.iastate.edu/~dicook\">Di Cook</a></font> </th>  \n</tr>\n<tr>\n<th align=left><font size=-1><a href=\"http://www.biostat.ku.dk/~pd\">Peter Dalgaard</a></font></th>\n<th align=left><font size=-1><a href=\"http://www.stat.auckland.ac.nz/rgentlem/rgentlem.html\">Robert Gentleman</a></font> </th>\n<th align=left><font size=-1><a href=\"http://www.ci.tuwien.ac.at/~hornik/\">Kurt Hornik</a></font></th>\n</tr>\n<tr>\n<th align=left><font size=-1><a href=\"http://www.stat.auckland.ac.nz/PEOPLE/ihaka/rihaka.html\">Ross Ihaka</a></font>  </th>\n<th align=left><font size=-1><a href=\"http://www.ci.tuwien.ac.at/~leisch/\">Friedrich Leisch</a></font> </th>\n<th align=left><font size=-1><a href=\"http://www.biostat.washington.edu/~thomas/\">Thomas Lumley</a></font></th>\n<tr>\n<th align=left><font size=-1><a href=\"http://stat.ethz.ch/~maechler/\">Martin  M&auml;chler</a></font></th>\n<th align=left><font size=-1><a href=\"http://sirio.stat.unipd.it/\">Guido Masarotto</a></font></th>  \n<th align=left><font size=-1><a href=\"http://www.stat.auckland.ac.nz/PEOPLE/paul/paul.shtml\">Paul Murrell</a></font></th>\n</tr>\n<tr>\n<th align=left><font size=-1><a href=\"http://www-stat.stanford.edu/~naras/\">Balasubramanian Narasimhan</a></font></th>  \n<th align=left><font size=-1><a href=\"http://www.stats.ox.ac.uk/~ripley/\">Brian Ripley</a></font></th>\n<th align=left><font size=-1><a href=\"http://www.statlab.uni-heidelberg.de/people/sawitzki/\">G&uuml;nther  Sawitzki</a></font></th>\n</tr>\n<tr>\n<th align=left><font size=-1><a href=\"http://www.stat.ucdavis.edu/~duncan/\">Duncan Temple Lang</a></font></th>\n<th align=left><font size=-1><a href=\"http://stat.umn.edu/~luke/\">Luke Tierney</a></font> </th>\n<th align=left><font size=-1><a href=\"http://www.cmis.csiro.au/bill.venables/\">Bill Venables</a></font></th>\n</tr>\n</table>\n</center>\n<p>\nParticipation in the general and special-purpose software work of the\nOmega project is open to anyone interested in our goals.\nThe <a href=\"http://www.omegahat.net/mailman/listinfo/\">mailing\nlists</a> are a good place to start; in particular\n<a name=\"NWD1\"></a>\n<a href=\"mailto:omega-devel@omegahat.net\">omega-devel@omegahat.net</a>\nis a list for discussion of the general development of software\nfor the project.\nThe success of the  Omega project is highly dependent on the\ninvolvement of a wide range of participants in many different areas.\nWe can all benefit.\n<p>\n\n<h2>The Omega Project Umbrella</h2>\n\nAs well as developing software ourselves,\nthe project also hopes to support other development efforts.\nTo this end, Doug Bates has generously allowed his machine to be used\nfor distributing code for different projects.\nThese projects include.\n<ul>\n  <li> <a href=\"contrib/RS-DBI/index.html\">RS-DBI: Database\n      connectivity for both R and S.</a>\n</ul>\nMore general details are <a href=\"contrib/index.html\">also available</a>.\n\n</body> </html>\n"
