[R] pairs(x)

[Adaikalavan Ramasamy]

The following is adapted from help(pairs) :

lpanel <- function(x, y){ points(x, y, col=2, pch=".") }
upanel <- function(x, y){ points(x, y, col=3, pch="x") }
data <- matrix( rnorm(300), nc=3 )
colnames(data) <- paste("Column", LETTERS[1:3])
pairs(data, upper.panel=upanel, lower.panel=lpanel)
