R Montreal 2018 is the second edition (after “R à Québec 2017”) of an R users conference in Québec/Canada. The objective of the workshop is to bring together the community of Canadian R users. The workshop will be a bilingual conference French/English. Tutorials will be offered the first day (introduction to R, intermediate level, advanced level) while the second and third days will be the opportunity to listen to new advances in R in different statistical topics (such as machine learning, bioinformatics, finance and insurance, biostatistics, public health, spatial statistics) as well as more general subjects such as R programming, vizualization, big data manipulation. Three plenary speakers are already scheduled and a call for contributed talks, lightning talks and poster presentations will be effective in January 2018.
