imf.gam R Documentation
Inverse map function for gamma renewal model
Description
Calculates the genetic length (in cM) corresponding to a particular
recombination fraction for the gamma renewal model for recombination at
meiosis.
Usage
imf.gam(r, nu=1, tol=1e-12)
Arguments
r
Recombination fraction, potentially a vector.
nu
Interference parameter (nu = m+1 in the chi-square
model; nu=0 is NI).
tol
Tolerance for doing numerical integration and finding root.
Details
Uses uniroot to solve the r = mf.gam(d,
nu).
Value
Vector of interval lengths (in cM), of same length as the input r.
