estimateMap | Estimate map distances
estimateMapFromImputation | Re-estimate large gaps in a genetic map from IBD genotype imputations
estimateRF | Estimate pairwise recombination fractions This function estimates the recombination fractions between all pairs of markers in the input object. The recombination fractions are estimated using numerical maximum likelihood, and a grid search. Because every estimate will be one of the input test values, the estimates can be stored efficiently with a single byte per estimate.
