Your question is ambiguous. You have shown the layout with names that are not valid column names. You may want to use barplot() rather than plot(), since your x-values are discrete.
I see only the chromosomes with numbers but not those with letter (x and y). What can I do? A second question: How can I add a single line in that plot at a certain y-level.
If you do not want barplot() then look at dotplot().
