R course: Advanced modules

>> Register here by April 9, 2015

Category: Skill course
Credit points: 0.2 per day

1.  Concept

This modular seminar addresses everybody who is interested in improving existing R skills.

This seminar is also intended as a preparation for the course in applied statistics and data analysis, which requires some scripting skills.

There will be

  • a little theory
  • focus on technical aspects (not on interpretation)
  • time for questions and answers
  • hands-on training based on the requests you write in the comment field of the registration form. Feel free to approach us with your data

Prerequisites: Basic knowledge of a language of scientific computing: R, Matlab (exercises will be in R) which are taught in the course 'R - The basics'

2.  Place and time

  • When? April 20-24, 2015
  • Where? MPI for Biogeochemistry, Seminar room B0.002

3.  Registration

  • Register here by April 9, 2015.

4.  What you need to prepare

Please make sure that a recent version of R is running on your laptop.
You can download the most recent version here: http://www.r-project.org/
RStudio is a new open-source integrated development environment that runs on all platforms. It nicely combines console, script editor, working directory, plots etc. into a an uncluttered layout that you can easily navigate. You need to have R installed before you can use RStudio as a development environment.

Please also make sure that you can access the internet via WLAN (BGC-users, if you have a BGC-account; BGC-guests, if you don't have an account)
