So instead of altering the point character (pch), we alter the colors. HTH, Marc Schwartz

Here is a completely different solution using gplot in sna. We create an edge matrix, edges, and plot it. library(sna) edges <- replace(matrix(0, 8, 8), cbind(match(x0, xx), match(x1, xx)), 1) gplot(edges, coord = cbind(xx, yy), usearrows = FALSE, vertex.col = c("black", "white")[factor(aa)]) On 10/15/06, Michael Kubovy <kubovy at virginia.edu> wrote:> Dear r-helpers, > > xx <- c(0.000, 0.210, 0.714, 0.514, 1.000, 0.190, 0.590, 0.152) > yy <- c(0.000, 0.265, 0.256, 0.521, 0.538, 0.761, 0.821, 1.000) > aa <- c(19, 19, 19, 21, 19, 21, 21, 21) > x0 <- xx[c(1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 5, 6, 6, 7)] > y0 <- yy[c(1, 1, 2, 2, 2, 3, 3, 4, 4, 4, 5, 6, 6, 7)] > x1 <- xx[c(2, 3, 3, 4, 6, 4, 5, 5, 6, 7, 7, 7, 8, 8)] > y1 <- yy[c(2, 3, 3, 4, 6, 4, 5, 5, 6, 7, 7, 7, 8, 8)] > > plot(yy ~ xx, pch = aa, cex = 3) > segments(x0, y0, x1, y1) > > Can anyone suggest a way of insuring that the lines are hidden behind > the unfilled circles? > _____________________________ > Professor Michael Kubovy > University of Virginia > Department of Psychology > USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 > Parcels: Room 102 Gilmer Hall > McCormick Road Charlottesville, VA 22903 > Office: B011 +1-434-982-4729 > Lab: B019 +1-434-982-4751 > Fax: +1-434-982-4766 > WWW: people.virginia.edu/~mk9y > > ______________________________________________ > R-help at stat.math.ethz.ch mailing list > stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. >
