setStatistics {hapFabia} | R Documentation

## Computes and stores the statistics of an IBD segment list

### Description

`setStatistics`: R implementation of `setStatistics`.

Computes the statistics of an IBD segment list given as an object of the class `IBDsegmentList`. In the slot `statistics` of an object of the class `IBDsegmentList` the summary statistics across the list of IBD segments are stored. Following characteristics are stored in the list `statistics`:

1. "avIBDsegmentPosS": physical position

2. "avIBDsegmentLengthSNVS": length in SNVs

3. "avIBDsegmentLengthS": length in bp

4. "avnoIndividS": number individuals

5. "avnoTagSNVsS": number tagSNVs

6. "avnoFreqS": tagSNV frequency

7. "avnoGroupFreqS": tagSNV group frequency

8. "avnotagSNVChangeS": tagSNV change between minor and major allele

9. "avnotagSNVsPerIndividualS": tagSNVs per individual

10. "avnoindividualPerTagSNVS": individuals per tagSNV.

### Usage

    ## S4 method for signature 'IBDsegmentList'
    setStatistics(IBDsegmentList)

### Arguments

`IBDsegmentList` | object of class `IBDsegmentList`.

### Details

The list can be extended by the user.

Implementation in R.

### Value

object of class `IBDsegmentList` with statistics set
