Notes from eRum 2018: European R User Conference in Budapest

The second eRum was organized this year in Budapest (Hungary) and gathered ~500 participants (mostly, but not only, from Europe). It was a great event and a worthy successor of the first eRum organized in Poznań (Poland) two years ago. In the Workskop Day I participated in two workshops: Efficient R programming by Colin Gillespie (author of the Efficient R Programming book by O’Reilly) Building a package that lasts by Colin Fay.

Hadley Wickham has been a prime mover in releasing R upon the masses, enabling hordes of unsuspecting would-be researchers to process and visualize data in ways they never dreamed of. The tidyverse, the culmination of years of effort in the R language, is a universe of packages that facilitate a grammar of data, graphics, and modeling that allows even beginners to speak the language of data science fluently.

Presentation of R package LimeRick on eRum

UPDATE: The online static version of the presentation is available here: http://rpubs.com/kalimu/erum. Thank you for all the feedback! In two days, from 12 to 14 October, 2016 in Poznan (Poland) will take place the conference “eRum 2016: european R users meeting“. I will give a talk about new R package: LimeRick. LimeRick enables close connection between two important open-source projects: R and LimeSurvey. LimeSurvey is the most advanced open-source system for on-line survey and Computer Aided Web Interviewing (CAWI) and together with R they offer advanced ecosystem for gathering and analyzing declarative data.
