mf.gam: Map function for gamma renewal model

In kbroman/ricalc: Calculations for Recombinant Inbred Lines

Map function for gamma renewal model

Description

Calculates the recombination fraction corresponding to a particular cM interval length for the gamma renewal model for recombination at meiosis.

Usage

mf.gam(d, nu=1, tol=1e-12)

Arguments

d	Interval length (in cM), potentially a vector.
nu	Interference parameter (nu = m+1 in the chi-square model; nu=0 is NI).
tol	Tolerance for doing numerical integration.

Details

Uses the function integrate to do numerical integration.

Value

Vector of recombination fractions, of same length as the input d.
