some pairs() questions

From: Pieter Provoost

I'm sure it's possible to display the variable names by making a small
change to the code. Someone did this last week but I can't 
contact this
person now to ask how. I tried this

vars <- names(Rdata)
pairs(Rdata, labels=vars,...)

but that doesn't work (formal argument "labels" matched by 
multiple actual
arguments). Unfortunately I don't have the time right now to 
get to know new
packages and write new scripts...

Thanks
Pieter

(Lazy answer, not checking your code in detail)

Try using splom() in the lattice package, as it gives more extensive

control

to do the sorts of things you seem to want.

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,
