summary.map: Summary of marker map information
In synbreed: Framework for the Analysis of Genomic Prediction Data using R

Description Usage Arguments Details Value Author(s) See Also Examples

This function can be used to summarize information from a marker map in an object of class gpData. Return value is a data.frame with one row for each chromosome and one row summarizing all chromosomes.

1	summaryGenMap(map, cores=1)

`map`	`data.frame` with columns `chr` and `pos` or a `gpData` object with element `map`
`cores`	`numeric`. Specifies the number of cores for parallel computing.

Summary statistics of differences are based on euclidian distances between markers with non-missing position in map, i.e. pos!=NA.

A data.frame with one row for each chromosome and the intersection of all chromosomes and columns

`noM`	number of markers
`range`	range of positions, i.e. difference between first and last marker
`avDist`	avarage distance of markers
`maxDist`	maximum distance of markers
`minDist`	minimum distance of markers
