[R] contour

[Rui Barradas]

Hello,

Follow the code below and see what's the right way:


d <- read.table(text="
x1 x2 x3
0   1    2
0   2    1
0   3    5
1   1    4
1   2    2
1   3    3
", header=TRUE)

x3 <- matrix(d[, "x3"], ncol=2)
levels <- sort(unique(x3))
contour(0:1, 1:3, t(x3), levels=levels)


Hope this helps,

Rui Barradas
