maftools - An R package to summarize, analyze and visualize MAF files

GitHub closed issues R-CMD-check

Introduction

maftools provides a comprehensive set of functions for processing MAF files and to perform most commonly used analyses in cancer genomics. See here for a detailed usage and a case study.

Installation

#Install from Bioconductor repository
BiocManager::install("maftools")

#Install from GitHub repository
BiocManager::install("PoisonAlien/maftools")

Getting started: Vignette and a case study

A complete documentation of maftools using TCGA LAML as a case study can be found here.

Besides the MAF files, maftools also facilitates processing of BAM files. Please refer to below vignettes and sections to learn more.
