mfun: Mapping functions

In tpbilton/GUSMap: Genotyping Uncertainty with Sequencing Data and Linkage Mapping (GUSMap)

Mapping functions

Description

Transform recobination fractions into map distances using a specified mapping function.

Usage

mfun(rf, fun = "morgan", centiM = FALSE)

Arguments

rf	Vector of recombination fraction values
fun	Character vector giving the name of the mapping function (see details).
centiM	Logical value. If TRUE, the mapping distances returned are in centiMorgans. Otherwise, the mapping distances returned are in Morgans.

Details

Currrently, the mapping implemented are:

Morgan mapping function (fun="morgan")

d = r

Haldane mapping function (fun="haldane")

d = -(1/2)ln(1 - 2r)

Kosambi mapping function (fun="kosambi")

d = (1/4)ln((1+2r)/(1-2r))

where r denotes the recombination fraction value and d denotes the mapping distance value.
