Computing in R (Doctoral School)

Computing in R (Amsterdam UMC Doctoral School)

This course is part of the PhD course program of the Amsterdam UMC Doctoral School.

• Location: Lecture hall 5 (Mo, Th), lecture hall 3 (Tu), lecture hall 1 (Fr); AMC
• ECTS: 0.4
• Teachers: Perry Moerland (coordinator, p.d.moerland@amsterdamumc.nl), Aldo Jongejan, Michel Hof and Thanos Angelakis

Goal

R is a simple programming language for statistical computing. Due to its flexibility and the large variety of statistical functions available in R, it is a popular alternative for programs like SPSS. However, for a beginner mastering R can be rather difficult. This course helps the student to become familiar with the basics of R. After the course the student will be able to write short programs in R for basic (data) analyses and for plotting figures.
