ADVANCED COURSE: INTRODUCTION TO R

June 19-23 , 2017 | CIBIO-InBIO, Vairão, Portugal

 

The R language for statistical computing is a freely available, comprehensive statistical package with excellent graphical capabilities. As such, it has become an indispensable tool in all fields of biological research: many new statistical methods have been developed in recent years using R and numerous top-rank journals nowadays favor its use for the publication of scientific results.

 

The objective of this short course is to provide a general introduction towards using R for data analyses. We will provide a general review of basic operations, data types and management, aiming at familiarizing the students with the R environment without requirement of prior experience in R or programming. The course will follow a hands-on approach, with a theoretical background previous to each practical session.
This course will provide the basis for more advanced courses on specific topics using R, and it will be a requirement for students interested in enrolling in those courses.
