Read label information from a file
name of the tsv file containing labels
label object containing several entries:
$label named vector containing the numerical labels from the
$info information about the classes in the label;
$type information about the label type (e.g.
This function reads in a tsv file with labels and converts it into a label.
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
