read.label {SIAMCAT} | R Documentation

## Read label file

### Description

Read label information from a file

### Usage

    read.label(fn.in.label)

### Arguments

`fn.in.label` | name of the tsv file containing labels

### Details

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

### Value

label object containing several entries:

- `$label` named vector containing the numerical labels from the file;

- `$info` information about the classes in the label;

- `$type` information about the label type (e.g. `BINARY`);

### Examples

    # run with example data
    fn.label <- system.file('extdata',
        'label_crc_zeller_msb_mocat_specI.tsv',
        package = 'SIAMCAT')

    crc.zeller.label <- read.label(fn.label)
