have a look at segments(), e.g., x <- rnorm(5) y <- rnorm(5) z <- rnorm(5) w <- rnorm(5)
r1 <- range(x, z) r2 <- range(y, w) plot(r1, r2, type = "n") points(x, y) points(z, w, pch = 19) segments(x, y, z, w) I hope it helps. Best, Dimitris William Simpson wrote:
I would like to do as follows plot(a,b) points(c,d,pch=19) Now join with a line segment point a[1], b[1] to c[1], d[1]; a[2], b[2] to c[2], d[2] ... a[n], b[n] to c[n], d[n] All corresponding points from the two data sets are joined by line segments. Thanks very much for any tips on how to do this.
