Download the large data objects of the package

The three largest objects (filtered_txi, dds and zscore_mat) are not installed with the package, to keep it small. They are stored as files of the GitHub release of the package, and this function downloads them the first time they are used. Later calls read the copy saved on your computer, so no internet connection is needed.

Usage

download_data(name = c("filtered_txi", "dds", "zscore_mat"), tag = "v0.1.0")

Arguments

name: Name of the object: "filtered_txi", "dds" or "zscore_mat".
tag: GitHub release that contains the files. The default is the release with the data used in the lessons.

Value

The requested object.

Details

Files are saved in tools::R_user_dir("GeneExprLupusMx", "cache"). Delete that folder to free space or to download them again. The first download needs about 46 MB in total.

Note

Several other packages (e.g., FedData, admixr and tidyfinance) also have a function called download_data(). If you load one of them together with GeneExprLupusMx, the one loaded last is used. To make sure you use this one, call it as GeneExprLupusMx::download_data().

Examples

if (FALSE) { # interactive()
filtered_txi <- download_data("filtered_txi")
dim(filtered_txi$counts)
}
