# LDcorSV

### Description

The package provides a set of functions which aim is to propose four measures of linkage disequilibrium:

- `Measure.R2`

: the usual *r^2* measure.

- `Measure.R2S`

: *r^2* corrected by the structure of the sample (*r^2_S*).

- `Measure.R2V`

: *r^2* corrected by the relatedness of genotyped individuals (*r^2_V*).

- `Measure.R2VS`

: *r^2* corrected by both the relatedness of genotyped individuals and the structure of the sample (*r^2_VS*).

- `LD.Measures`

: this function computes the four measures of linkage disequilibrium (*r^2*,*r^2_V*,*r^2_S* and *r^2_{VS}*) for a set of loci and gives extra information about them.
