lattice -- panel order display

Here is a 'subset' of the ' test ' data .

xyplot ( number ~ cm | as.factor(test$year) , data=test)

test

    year cm number
34  1995 72     34
35  1995 73     37

R-help,

I'm using 'xyplot' in lattice package which plots length frecuencies

by

year (10).
The order I get is not logical and the 'index.cond' argument to
'xyplot' is a bit cumbersome when it comes to plot a great deal of

(in

my case years).

I have tried sorting the conditioning variable but still get the

same

result.

Is there any easy way to do it without making use of 'index.cond' ?

The function call is as follows:

xyplot ( number ~ cm | as.factor(test$year) , data=test)

Not reproducible for us, we don't have "test", so please make your 
example small and reproducible.

Thanks in advance
