Data for the PhysioNet Sepsis Challenge is distributed as pipe separated
values (.psv
) files, split into separate files per patient ID, containing
time stamped rows with measured variables as columns. Files are named with
patient IDs and do not contain any patient identifiers as data. Functions
read_psv()
and write_psv()
can be used to read from and write to such
a data format.
While write_psv()
is called for side effects and returns NULL
invisibly, read_psv()
returns an object inheriting from id_tbl
.
