The purpose of this tutorial is to provide an overview of the facilities implemented by different R packages to learn Bayesian networks, and to show how to interface these packages [1-3]. As a motivating example, we will reproduce the analysis performed by Sachs et al.  to learn a causal protein-signalling network.
The tutorial aims to introduce the basics of Bayesian networks' learning and inference using real-world data to explore the issues commonly found in graphical modelling.
The tutorial will cover the following topics, with particular attention to R coding practices.
Background knowledge required for this tutorial includes basic probability theory (multinomial and normal distributions in particular) and basic R commands.
Target audience includes researchers and analysts working on data that can be intuitively modelled as networks. Practicioners working in life sciences can relate best with the motivating example, but the techniques covered in the tutorial can easily be applied to other fields such as social sciences .
