R help - Nov 2010 - Removing tick marks and Adding labels to lattice plots

Hi all, 

I am trying to remove the current labels of the tick marks and replace them
with text using xyplot within lattice


right now I have tick marks at 1, 1.5, 2, 2.5, 3 I would like to transform
them to say 'T1', 'T2', 'T3' 


thanks in advance
Kathleen

In the xyplot documentation you will find the controls for ticks and  
labels in the scale section. You have not given a well-formed example   
because the number of labels does not align with the number of ticks  
so I am going to assume there are currently 5 ticks to be relabeled.  
Perhaps something along these lines:

xyplot( <some-formula> ,
          data=<dfrm,
           scales=list(x=list(labels=c('T1', 'T2', 'T3'
, 'T4',
'T5'))) )

Notice the way the arguments are all packaged as nested lists. That  
the way lattice works.
