write_manifest: write a manifest data.frame to disk
Description
The manifest method creates a data.frame
that represents the data for a manifest file needed
by the GDC Data Transfer Tool. While the file format
is nothing special, this is a simple helper function
to write a manifest data.frame to disk. It returns
the path to which the file is written, so it can
be used "in-line" in a call to transfer.
Usage
write_manifest(manifest, destfile = tempfile())
Arguments
manifest
A data.frame with five columns, typically
created by a call to manifest
