[R] Suppresing default text in pairs.lmList() in package = nlme

[Michael Kubovy]

Thanks Ken and Dieter,

I added xlab = '' and the text 'Scatter Plot Matrix' produced by pairs 
() applied to an lmList object (in nlme) went away. Skip the rest ---  
which is mainly autobiographical --- unless you're curious.

Overnight I flew to New York (a slightly more left-leaning state),  
bought a new computer, installed R and all the packages, and then  
flew back with the new machine; the symptom remained  ;)

Is it documented somewhere how to figure this out? It just didn't  
occur to me that the problem was as simple as changing the xlab and I  
don't yet have the habit of looking at code. Nevertheless I had done  
the following:

 > pairs
function (x, ...)
UseMethod("pairs")
<environment: namespace:graphics>

... which did not make me happy. So then I tried:

 > pairs.lmList
Error: object "pairs.lmList" not found

... which did not make me happy. So then I tried:

 > apropos('pairs')
[1] "pairs"         "pairs.default" "panel.pairs"
 > pairs.default
function (x, labels, panel = points, ..., lower.panel = panel,
...

... and then my eyes glazed over because nothing I saw seemed relevant.
