Read and write utilities
Description
Support for reading from and writing to pipe separated values (.psv
)
files as used for the PhysioNet Sepsis Challenge.
Usage
write_psv(x, dir, na_rows = NULL)
read_psv(dir, col_spec = NULL, id_var = "stay_id", index_var = NULL)
Arguments
x |
Object to write to files |
dir |
Directory to write the (many) files to or read from |
na_rows |
If |
col_spec |
A column specification as created by |
id_var |
Name of the id column (IDs are generated from file names) |
index_var |
Optional name of index column (will be coerced to
|
Details
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.
Value
While write_psv()
is called for side effects and returns NULL
invisibly, read_psv()
returns an object inheriting from id_tbl
.
