I don't think there is good way to do this in the way you expect (I'm 
assuming you want the same axis limits for each panel). If you really 
want this, look at the following options:

1. You can specify the limits, tick positions, and axis labels 
individually for each panel (see documentation for 'scales' in ?xyplot; 
all the relevant components - at, lab, etc - can be lists). Use this in 
conjunction with relation = "free". You need to supply empty strings as 
labels for all the 'inside' panels.

2. The big problem this would have is that the same amount of space 
would be allocated for the axis labels in each of the panels, even if 
that space is not used for the inside ones. One (undocumented and 
unreliable) way to get around that would be to use negative values of 
'between'.

Hope that helps,
