add3pt: Add markers to a framework map using 3-point likelihoods
In mpMap: Multi-parent RIL genetic analysis

Description Usage Arguments Details Value See Also

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.

1 2	add3pt(mpcross, newmpcross, newchr, mapfx = c("haldane", "kosambi"))

`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

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

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.
