R Bioinformatics Cookbook

By: Dan MacLean

Overview of this book

Handling biological data effectively requires an in-depth knowledge of machine learning techniques and computational skills, along with an understanding of how to use tools such as edgeR and DESeq. With the R Bioinformatics Cookbook, you’ll explore all this and more, tackling common and not-so-common challenges in the bioinformatics domain using real-world examples. This book will use a recipe-based approach to show you how to perform practical research and analysis in computational biology with R. You will learn how to effectively analyze your data with the latest tools in Bioconductor, ggplot, and tidyverse. The book will guide you through the essential tools in Bioconductor to help you understand and carry out protocols in RNAseq, phylogenetics, genomics, and sequence analysis. As you progress, you will get up to speed with how machine learning techniques can be used in the bioinformatics domain. You will gradually develop key computational skills such as creating reusable workflows in R Markdown and packages for code reuse. By the end of this book, you’ll have gained a solid understanding of the most important and widely used techniques in bioinformatic analysis and the tools you need to work with real biological data.

Retrieving gene and genome annotation from BioMart

Once a draft of a genome sequence is prepared, a lot of bioinformatics work goes into finding the genes and other functional features or important loci that are in a genome. These annotations are numerous, difficult to perform and verify, typically take lots of expertise and time, and are not something we would want to repeat. So, genome project consortia will typically share their annotations in some way, often through public databases of some sort. BioMart is a common data structure and API through which annotation data is made available. In this recipe, we'll look at how to programmatically access such databases so we can get annotations for genes that we are interested in.
