[R] How to stack two Stack manhattan plots?

[cpoiw@rt m@iii@g oii chemo@org@uk]

What did you expect?

I'm assuming two plots (based on the subject) and side by side based on 
the code (nrow =1)

But you are getting several graphs (facets) on the row and only expected 
2?

What is in CHR?  i.e. summary(tmp1$CHR)

I'm assuming its not a factor with 2 elements...?
