genetic_map: Multi-point estimation of a genetic map

In jendelman/MapRtools: Tools for genetic mapping

Multi-point estimation of a genetic map

Description

Multi-point estimation of a genetic map

Usage

genetic_map(x, LOD, n.point = 5)

Arguments

x	matrix of pairwise map distances (cM) between the marker-bins for one chromosome
LOD	matrix of LOD scores between marker-bins
n.point	Number of points used for estimation

Details

Uses LOD-score weighted least-squares regression method described by Stam (1993). Markers must be binned (e.g., using LDbin) for this function to work properly. Argument n.point controls how many pairwise distances are used in the linear regression. n.point=2 means only adjacent bins; n.point=3 means adjacent bins and bins with one intervening marker, etc. Marker names taken from the rownames attribute of x.

Value

data frame with columns marker,position (in cM)
