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.

Extracting information in genomic regions of interest

Very often, you'll want to look in more detail at data that falls in a particular genomic region of interest, whether that be the SNPs and variants in a gene or the genes in a particular locus. This extremely common task is handled very well by the extremely powerful GRanges and SummarizedExperiment objects, which are a little fiddly to set up but have very flexible subsetting operations that make the effort well worth it. We'll look at a few ways to set up these objects and a few ways we can manipulate them to get interesting information.

Getting ready

In this recipe, we need the GenomicRanges, SummarizedExperiment, and rtracklayer Bioconductor packages. We&apos...
