## Data for the book

We rely on data from different R and Bioconductor packages throughout the book. For the datasets that do not ship with those packages, we created our own package compGenomRData. You can install this package via devtools::install_github("compgenomr/compGenomRData"). We use the system.file() function to get the path to the files. We noticed many inexperienced users are confused about this function. This function just outputs the full path to the file that is installed with the data package.
