computemap: Computes map distances
Description
Given an mpcross object with a map order and matrix of
recombination fractions, this function will estimate map
positions
Usage
computemap(object, mapfx = c("haldane", "kosambi"), missfx = 2)
Arguments
object
Object of class mpcross
mapfx
Map function to convert recombination
fractions to cM
missfx
Function to impute missing recombination
fraction values
Value
An mpcross object is returned whose map component has
been estimated based on the map order and matrix of
recombination fractions. Missing recombination fractions
are imputed either by filling in the closest non-missing
value (missfx=1) or by averaging the distance between
other nearby markers (missfx=2).
