locate_xo: Locate crossovers
In rqtl/qtl2geno: Treatment of Marker Genotypes for QTL Experiments

Description Usage Arguments Value Examples

Estimate the locations of crossovers in each individual on each chromosome.

1	locate_xo(geno, map, quiet = TRUE, cores = 1)

`geno`	List of matrices of genotypes (output of `maxmarg()` or `viterbi()`).
`map`	List of vectors with the map positions of the markers.
`quiet`	If FALSE, print progress messages.
`cores`	Number of CPU cores to use, for parallel calculations. (If `0`, use `parallel::detectCores()`.) Alternatively, this can be links to a set of cluster sockets, as produced by `parallel::makeCluster()`.

A list of lists of estimated crossover locations, with crossovers placed at the midpoint of the intervals that contain them.
