I'm guessing that you meant to write: latticeExtra

The help page for xyplot has information about the scales argument  
which is what you should constructing when you want to modify the plot  
axis annotation in lattice functions.

perhaps something like scales=list(
                                 x=list(at=1:5, labels=c('May' ,  
'June','July','August','September') ),
                                 y=list(at=(-8):-1,  
labels=c('T','N','C','B','KC','FB','SF','MO'))
                                   )
