Description
This is an introductory course to R programming.
The course is offered in 3 slow-paced practicums for absolute beginners. The goal is to offer a good base with a lot of hands on exercises.
We will use R Studio on the server of the CRG.

We will use the R Studio server of the CRG. We will go through what can be done with R Studio, from file and folders manipulation/navigation, to getting help on R functions. - Basics of R
Syntax, special characters, create an object, manipulate the object, simple arithmetics. - Functions usage in R
Arguments. Get help. - R scripts: write and save commands, run them as a block. Comment code.
- Data types.
- Vectors
Basic (and most important) data structure in R. We will learn how to create, modify, subset, manipulate, compare vectors. - Input / output
Reading in and writing out. Changing directory. - Introduction to factors: categorical vectors.
- Missing values: how to deal with NA values.
- Introduction to R Studio
