From R to Machine Learning; an introductory course

This learning path aims to teach you the basics of Machine Learning using R. Initially you will learn how to code in R within the Galaxy platform, gaining some familiarity into how to wrangle and analyze data. Then, you will be guided through the various types of Machine Learning techniques, developing some simple models using R.

Learning objectives:

Module 1: R in Galaxy

  • Know advantages of analyzing data using R within Galaxy.
  • Compose an R script file containing comments, commands, objects, and functions.
  • Be able to work with objects (i.e. applying mathematical and logical operators, subsetting, retrieving values, etc).
  • Be able to load and explore the shape and contents of a tabular dataset using base R functions.
  • Understand factors and how they can be used to store and work with categorical data.
  • Apply common dplyr functions to manipulate data in R.
  • Employ the ‘pipe’ operator to link together a sequence of functions.

Module 2: Machine Learning using R

  • Understand the ML taxonomy and the commonly used machine learning algorithms for analysing -omics data
  • Understand differences between ML algorithms categories and to which kind of problem they can be applied
  • Understand different applications of ML in different -omics studies
  • Use some basic, widely used R packages for ML
  • Interpret and visualize the results obtained from ML analyses on omics datasets
  • Apply the ML techniques to analyse their own datasets
