Download a Sample of RNA-seq Files from S3

Downloads a subset of RNA-seq files from the public MMRF CoMMpass S3 bucket. This function is useful for testing and development with a small sample of data before downloading the full dataset. Files are downloaded using anonymous access to the public bucket.

Usage

download_s3_subset(s3_paths, dest_dir = "data/raw/rna_seq", n = 3)

Arguments

s3_paths

Character vector of S3 object keys (file paths) to download from

dest_dir

Destination directory for downloaded files (default: "data/raw/rna_seq")

n

Number of files to download (default: 3)

Value

Character vector of successfully downloaded file paths
