find_markerpos {qtl2}

Find positions of markers

Description

Find positions of markers within a cross object

Usage

find_markerpos(cross, markers, na.rm = TRUE)

Arguments

cross

Object of class "cross2". For details, see the R/qtl2 developer guide. Can also be a map (as a list of vectors of marker positions).

markers

A vector of marker names.

na.rm

If TRUE, don't include not-found markers in the results (but issue a warning if some markers weren't found). If FALSE, include those markers with NA for chr and position.

Value

A data frame with chromosome and genetic and physical positions (in columns "gmap" and "pmap"), with markers as row names. If the input cross is not a cross2 object but rather a map, the output contains chr and pos.
