| convert2sa {qtl} | R Documentation |
Convert a sex-specific map to a sex-averaged one, assuming that the female and male maps are actually the same (that is, that the map was estimated assuming a common recombination rate in females and males).
convert2sa(map, tol=1e-4)
map |
A map object with sex-specific locations (but assuming that
the female and male maps are the same), as output by the function
est.map for a 4-way cross, with argument
sex.sp=FALSE. |
tol |
Tolerance value for inspecting the differences between the female and male maps; if they differ by more than this tolerance, a warning is issued. |
We pull out just the female marker locations, and give a warning if there are large differences between the female and male maps.
A map object, with sex-averaged distances.
