## Estimate Jacquard condensed identity coefficients

### Description

Estimate Jacquard condensed identity coefficients by identity-by-state (IBS) from genotypic data.

### Usage

    ibs(x)

### Arguments

`x` | Genotype data with genotypes ("AA", "AB", "BB", or, 1, 2, 3) and without missing data, or probabilities for these genotypes (e.g., obtained by using `genoProb`). In case of genotype data, rows represent individuals and columns represent SNPs.

### Value

A matrix G with G[,j] being the j-th Jacquard identity coefficients.

### Note

Currently only support the two-allele data.
