When you call plot with more than two columns, uses the pairs() function.
That means you have to write a panel function. Here are a couple of
relatively simple examples:
pairs(variable[,2:4], panel=function(x, y, ...) text(x, y,
variable$group))
pairs(variable[,2:4], panel=function(x, y, ...) points(x, y,
pch=as.numeric(variable$group)))
The first one plots the group instead of a point and the second
one plots a symbol for each group.
