Intro to R course

This course aims to provide basic notions of R programming to people that have NEVER worked with R and that want to learn how to use it for data analysis and visualization.
If you already have some basic programming knowledge in other programming language, this course might be too basic for you.
The Introduction to R course starts from the very basics of R language, all the way through learning how to create scripts, read and write files, manipulate different data structures, which will allow you to learn how to do some basic analysis and and get familiar with this amazing programming language.You will learn how to efficiently manipulate different data structures, compute basic summary statistics and visualize the results. This will allow you to learn how to do some basic analysis and visualization of your own data by the end of the course. 

In this course we will combine explanations and examples with lots of hands-on that will allow you to get familiar with basic programming concepts and explore the different possibilities that R offers.

Topics that are going to be addressed:

• A basic introduction perfect for people that have never programmed before. 
• Learn the basis for data manipulation. 
• Plotting with ggplot.

What NOT to expect:  

• To learn about biostatistics tools 
• To learn about data cleaning or preprocessing
