<p>I am now looking for invitations to give a streamlined version of this talk privately to groups using <a rel="nofollow" href="https://www.r-project.org/" target="_blank"><code>R</code></a> who want to work with <a rel="nofollow" href="https://en.wikipedia.org/wiki/SQL" target="_blank"><code>SQL</code></a> (with databases such as PostgreSQL or big data systems such as Apache Spark). <code>rquery</code> has a number of features that greatly improve team productivity in this environment (strong separation of concerns, strong error checking, high usability, specific debugging features, and high performance queries).</p>
<p>If your group is in the San Francisco Bay Area and using <code>R</code> to work with a <code>SQL</code> accessible data source, please reach out to me at <a rel="nofollow" href="mailto:jmount@win-vector.com" target="_blank">jmount@win-vector.com</a>, I would be honored to show your team how to speed up their project and lower development costs with <code>rquery</code>. If you are a big data vendor and some of your clients use <code>R</code>, I am especially interested in getting in touch: our system can help <code>R</code> users start working with your installation.</p>
