R is a free, open-source software for statistical computing and graphics. In this course you will learn how to use this powerful tool for handling, analysing and displaying your data. You will analyse data by writing functions and scripts to get reproducible and well documented results. You will learn how to create excellent graphics and how to adapt them to your needs. We will use data from clinical background to work throughout the course. Main topics covered during this course will be: Basics of the R language, data accessing, data manipulations, explore and summarise your data using descriptive statistics, graphics in R, data analysis with focus on basic statistics (e.g. hypothesis testing, linear and logistic regression). Additional topics can be introduced, depending on the need and interest of participants (e.g. survival analysis and ROC curves).
