[R] some pairs() questions

I have a few problems with pairs(). I want to add the variables names to the plot, but I don't know how. I tried different things with the labels argument but nothing worked out. This is the code:

read.table("bay1.bay",header=T)->Rdata
(histogram part skipped)
pairs(Rdata,
pch='.',diag.panel=panel.hist,labels=NULL,gap=0,xaxt="n",yaxt="n",upper.pane l=NULL)

The other problem is that I want to "highlight" one or more of the records of Rdata (give it another symbol and another color). What's the easiest way to do this? The record to be highlighted should be selected based on the value of one of the variables (smaller than 2.8 is this case).

Many thanks in advance,
Pieter Provoost
