<h1>Summary of three years of the group activity</h1>
<p>At the beggining of the meeting, the initiator of the Warsaw R Enthusiasts Group, <a target="_blank" rel="nofollow" href="http://biecek.pl/">Przemysław Biecek</a>, gave a talk during which he summed up the last 3 years or our activities and presented main activities around R package in Poland in last several years.<br>
The presentation is available <a target="_blank" rel="nofollow" href="https://github.com/mi2-warsaw/SER/blob/master/histoRia/SER_Trzecie_Urodziny.pdf">here</a>.<br>
Attendees could learn some history of the R expansions in Poland and were introduced to R applications in Poland in fields like: insurances, technological industry, health service, weather forecasting.</p>
<blockquote>
<p>If you haven’t had a chance to see that presentation, you might consider attending next (20th) Poznań R Users Group (<a target="_blank" rel="nofollow" href="https://www.meetup.com/Poznan-R-User-Group-PAZUR/events/237450288/">PAZUR</a>) meeting (23rd March), where Przemysław will show a similar talk.</p>

<p><img src="https://i0.wp.com/r-addict.com/images/fulls/logo_whyR.jpg?w=456" data-recalc-dims="1"> This was the 24th gathering of our Warsaw R community. During those 3 years we grown so much that we exceeded 1300 users on our <a target="_blank" rel="nofollow" href="https://www.meetup.com/Spotkania-Entuzjastow-R-Warsaw-R-Users-Group-Meetup/">meetup group</a>. Together we have had 44 presentations, 13 workshops, 2 data analysis hackathons, 1 meeting with a machine learning videos from youtube, we have supported the organization of the <a target="_blank" rel="nofollow" href="http://erum.ue.poznan.pl/">European R Users Meeting</a> and we have started organizing Polish R Users Conference – <a target="_blank" rel="nofollow" href="http://whyr.pl/"><strong>Why R? 2017</strong></a>.</p>
<h1>Toast</h1>
<p>After the presentation we had a cake and the champagne. The toast for 3 consecutive years of successful meetings, raised more than 50 people.<br>
We even had the honor to host the representation of <strong>trigeR</strong> (<a target="_blank" rel="nofollow" href="https://www.meetup.com/Trojmiejska-Grupa-Entuzjastow-R/events/236257032/">TriCity R Enthusiasts Group</a>), <strong>STWUR</strong> (<a target="_blank" rel="nofollow" href="https://www.meetup.com/Wroclaw-R-Users-Group/">Wroclaw R Users Association</a>) and <a target="_blank" rel="nofollow" href="https://www.meetup.com/Spotkania-Entuzjastow-R-Warsaw-R-Users-Group-Meetup/events/237953300/">R-Ladies Warsaw Group</a> (that are co-organized next to Warsaw R Enthusiasts Group).<br>

<h1>Round tables session</h1>
<blockquote>
<p>Round table is a form of academic discussion. Participants agree on a specific topic to discuss and debate. Each person is given equal right to participate, as illustrated by the idea of a circular layout referred to in the term round table. – <a target="_blank" rel="nofollow" href="https://en.wikipedia.org/wiki/Round_table_(discussion)">Wikipedia</a></p>
</blockquote>
<p>As this is becoming more popular, we organized a round tables session with 6 various topics, including: R in education, R in business, Machine Learning, Shiny + Rmarkdown, R Freelancing, R integrations with other tools. Tables can be seen on this occasional photo of all attendees of the session. We planned a 1 hour long discussion but few tables lasted longer. Last attendees left the event almost 4 hours after we started the meeting.</p>

<h1>WRUG baseball jackets</h1>
<p>Yes! It’s not a coincidence that few people from a previous photo have the same outfit! For that occasion <a target="_blank" rel="nofollow" href="https://github.com/agosiewska">Alicja Gosiewska</a> and <a target="_blank" rel="nofollow" href="https://github.com/AleksandraDabrowska">Aleksandra Dąbrowska</a> (our new co-organizers) prepared baseball jackets of Warsaw R Enthusiasts Group. So far 21 participants have ordered such gifts. I appealed this initiative so much that I have decided to subsidize those baseball jackets a bit.</p>

<h1>wser.pl, a new logo and occasional stickers</h1>
<p>We went even further, and created (with a help of <a target="_blank" rel="nofollow" href="https://github.com/EmilBuszylo/">Emil Buszyło</a>) a new website of Warsaw R Enthusiasts Group (in polish: <em>Warszawskie Spotkania Entuzjastów R</em> (WSER)). It’s available here – <a target="_blank" rel="nofollow" href="http://wser.pl/">wser.pl</a> (still a little bit under construction). I am amazed by the timeline of our meetings. Baseball jackets, the website and occasional stickers were enriched by the new logo (by Klaudia Korniluk from <a target="_blank" rel="nofollow" href="https://www.facebook.com/pedzlenie/">Pędzlenie na zlecenie</a>).</p>
