remove.marker {onemap} | R Documentation |
Removes a genetic marker from a linkage group, i.e., from an object of
class extracted.group
.
remove.marker(w, mname = NULL)
w |
an object of class extracted.group . |
mname |
a character string indicating the name of the marker to be removed. |
Returns an object of class extracted.group
, which is a list
containing the following components:
marnames |
names of markers present in linkage group i ,
according to the original input file. |
number |
number of the linkage group, according to the numeration
in the object of class group from where the linkage group was
extracted. |
oriname |
name of the original object of class rf.2pts
used to generate the object of class group , i.e., containing
the results of two-point analyses. |
name |
name of the object of class group from where the
linkage group was extracted. |
Intended for dealing with ‘problematic’ markers, that is, markers whose position on the map is hard to estimate, or when linkage is uncertain.
