8th R-in-Grenoble working session

on the May 16, 2019

May, 16, from 16:00 to 18:00
The eighth working session of the Grenoble R community will be about "Data manipulation with package {dplyr}". Drinks and snacks are served during the second part of the session.

Each month, the Grenoble R-group organizes one working session of 2 hours, on Thursdays, from 16h-18h, at the Imag building.

Everyone is welcome from beginners to advanced R users. Participants just need to bring their laptop. Presentations or tutorials will last 30 to 60 min, on R topics that can be useful to many people, with practical examples. During the second part of the session, specific problems encountered by participants when coding in R will be discussed.

Drinks and snacks will be shared during the second part of the session.


May 16, 2019: Data manipulation with package {dplyr}

      Data manipulation is an essential step in any data analysis project. Core package of the tidyverse environment, {dplyr} provides a data manipulation framework that uses an intuitive syntax defined by a small set of verbs. In this tutorial we will learn how to pick observations by their values (filter()), reorder the rows (arrange()), pick variables by their name (select()), create new variables with functions of existing variables (mutate()), collapse many values down to a single summary (summarise()) and combine all these operations using the '%>%' (pipe) operator. This will help you solve the most common data manipulation challenges.
