Find positions of markers within a cross object
find_markerpos(cross, markers, na.rm = TRUE)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.
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).
A vector of marker names.
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.
find_marker()
iron <- read_cross2(system.file("extdata", "iron.zip", package="qtl2"))
# find markers
find_markerpos(iron, c("D8Mit294", "D11Mit101"))
