Prior to Cell Ranger 3.0 10x Genomics supported an R package, called rkit, that enabled users to load and manipulate 10X data. In the same manner, a more experienced person might want to refer to this book when needing to do a certain type of analysis, but having no prior experience. High-dimensional genomics datasets are usually suitable to be analyzed with core R packages and functions. The steps shown here just demonstrate one possible solution. The lessons below were designed for those interested in working with genomics data in R. If you had just gotten used to shell / biocluster, use this handy comparison between Linux and R. This is an introduction to R designed for participants with no programming experience. An R community blog edited by RStudio. Computational Genomics with R. Preface. The R environment includes a tremendous amount of statistical support that is both specific to genetics and genomics as well as more general tools (e.g., the linear model and its extensions). It also provides resources for future package developers to utilize existing classes and methods in creating new packages for population genetic analysis. BRGenomics is feature-rich and simplifies a number of post-alignment processing steps and data handling. Inspired by R and its community The RStudio team contributes code to many R packages and projects. However, due to the growth of third-party tools that provide similar capabilities, this package has been deprecated and it is unable to analyze data produced by the Cell Ranger 3.0 software.
