Add a marker to a cross
Add a marker to a cross object.
addmarker(cross, genotypes, markername, chr, pos)
cross |
An object of class |
genotypes |
Vector of numeric genotypes. |
markername |
Marker name as character string. |
chr |
Chromosome ID as character string. |
pos |
Position of marker, as numeric value. |
Use this function with caution. It would be best to incorporate new
data into a single file to be imported with read.cross.
But if you have genotypes on one or two additional markers that you
want to add, you might load them with read.csv
and incorporate them with this function.
The input cross object with the single marker added.
