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.

Completing read-to-reference alignment with external programs

The alignment of high-throughput reads is an important prerequisite for a lot of the recipes in this book, including RNAseq and SNP/INDEL calling. We looked at them in depth in Chapter 1, Performing Quantitative RNAseq, and Chapter 2, Finding Genetic Variants with HTS Data, but we didn't cover how to actually perform alignment. We wouldn't normally do this within R; the programs needed to make these alignments are powerful and run from the command line as independent processes. But R can control these external processes, so we'll look at how to run an external process so you can control them from within an R wrapper script, ultimately allowing you to develop end-to-end analysis pipelines.
