read.label {SIAMCAT} | R Documentation |
This file reads in the tsv file with labels and converts it into a label object.
First row is expected to be #BINARY:1=[label for cases];
-1=[label for controls]
.
Second row should contain the sample identifiers as tab-separated list
(consistent with feature and metadata).
Third row is expected to contain the actual class labels (tab-separated):
1
for each case and -1
for each control.
Note: Labels can take other numeric values (but not characters or strings); importantly, the label for cases has to be greater than the one for controls
read.label(fn.in.label)
fn.in.label |
name of the tsv file containing labels |
label object containing several entries:
$label

file;
$info

$type
information about the label type (e.g. BINARY
);
# run with example data fn.label <- system.file('extdata', 'label_crc_zeller_msb_mocat_specI.tsv', package = 'SIAMCAT') labels <- read.label(fn.label)
