R help - Mar 2002 - Formatting the output of pairs()

Would anyone be able to give me some ideas on how to go about changing
the output of pairs()?

What I want to do is :
 * plot each value as a point (instead of those hollow circles)
 * remove the gap between each scatter plot
 * make the frame around each scatter plot pale grey

Thanks for you time,

Hadley

Use the pch argument in pairs()

set gap = 0 in the pairs() command.

Hmm...not sure.

set argument panel. Don't known what you mean by a `point' (that would
be
invisible, but perhaps pch=20 or pch="."?

set argument gap.

In ... set bty="n", and in your panel function include
box(col="grey80").

E.g.

data(iris[, 1:4])
pairs(iris[, 1:4]), gap=0,
      panel=function(x,y, ...) {box(col="grey80"); points(x, y,
pch=20)},
      bty="n", diag.panel= function(x,y, ...)
box(col="grey80"))
