Setting up the pan T cell data

We download the data.

base.url <- "http://cf.10xgenomics.com/samples/cell-exp/2.1.0/t_3k/t_3k_raw_gene_bc_matrices.tar.gz"
tarball <- basename(base.url)
download.file(base.url, tarball, mode="wb")

We unpack it.

untar(tarball, exdir="t_3k")

And we clean up after ourselves.

unlink(tarball)
