mpMap (version 1.14)

add3pt: Add markers to a framework map using 3-point likelihoods

Description

Based on a framework map and chromosome assignments, markers are inserted at the midpoints of intervals. Positions are chosen by maximizing the 3 point likelihood.

Usage

add3pt(mpcross, newmpcross, newchr, mapfx = c("haldane", "kosambi"))

Arguments

mpcross

Object of class mpcross, with framework markers

newmpcross

Object of class mpcross, with additional markers

newchr

Set of chromosome listings for additional markers

mapfx

Map function to use - default is haldane

Value

Combination of the two mpcross objects with new markers inserted at midpoints of intervals with maximum LOD values if LOD > 3. Note that if markers are inserted at the same midpoint, it will be necessary to locally reorder them and then re-estimate the length of the map by summing adjacent recombination fractions.

Details

Note that the values in newchr need to correspond to the chromosomes already existing in mpcross.
