CESSARi project: Introduction to the R software for statistical computing

 

Welcome!


This course aims at addressing the basic aspects of proper data analysis using the R software for  statistical computing. It will follow a blended learning approach, i.e. we will combine phases of online learning and classroom teaching. On this website you will find the entire course material which will enable an individual course preparation on beforehand.


The course starts with an online meeting (via Zoom, link see below) on July 30th (6pm-7pm), with the aim to present the course outline and to give useful hints for the start. A 2-day classroom course on August 4th and 5th will conclude the workshop. The focus of this attendance course is on supervised hands-on exercises with the statistical software R.


The overall objective is to make you familiar with the usage of the R software for future research projects.

STATISTICAL DATA ANALYSIS: AN INTRODUCTION TO R and RSTUDIO

This course will introduce the practical use of the R software for statistical computing (www.r-project.org), and in particular how the RStudio environment is efficiently used.


Using RStudio requires to download both the R software and RStudio, and it is important to download and install the R software first. Under cran.rstudio.com you can select the appropriate download file according to your operating system (Windows, macOS, Linux). Having installed R, the download file for RStudio can be found at https://posit.co/download/rstudio-desktop/.
