calc_Lstar: Calculate adjusted chromosome length for an obligate chiasma.

In Meiosis: Simulation of Meiosis in Plant Breeding Research

Description

Calculate the reduced chromosome length that will give the target expected number of chiasmata when conditioning on there being at least one chiasma on the four-strand bundle.

Usage

calc_Lstar(L, m, p, epsilon = NULL)

Arguments

L	Double. Length of the chromosome in cM. Must be > 50.
m	Integer. The interference parameter (m = 0 is no interference).
p	Double. Proportion of chiasmata from no-interference mechanism. (p = 0 gives pure chi-square model)
epsilon	Double. The precision for finding the adjusted chromosome length. Defaults to NULL, where a reasonably "high" precision is used.

Details

This function is an R-wrapper of an underlying C++ routine. It is not intended for direct usage, but exposed for completeness.

Value

Double. Adjusted chromosome length.

Examples

Meiosis::calc_Lstar(100, 0, 0)
Meiosis::calc_Lstar(60, 10, 0.1)
