The default margins are set as lines below, left, top, and right using mar=c(5.1, 4.1, 4.1, 2.1). Just change the top margin something like 1.1:
par(mfrow=c(1,2), mar=c(5.1, 4.1, 1.1, 2.1)) --------------------------- David L.

If so, any help will be appreciated. Please use this code as an example: par(mfrow=c(1,2)) lizard <- c(6.2, 6.6, 7.1, 7.4, 7.6, 7.9, 8, 8.3, 8.4, 8.5, 8.6,8.8, 8.8, 9.1, 9.2, 9.4, 9.4, 9.7, 9.9, 10.2, 10.4, 10.8,11.3, 11.9) n.draw <- 100 mu <- 9 n <- 24 SD <- sd(lizard) draws <- matrix(rnorm(n.draw * n, mu, SD), n) get.conf.int <- function(x) { t.test(x)$conf.int } conf.int <- apply(draws, 2, get.conf.int) plot(range(conf.int), c(0, 1 + n.draw), type = "n", xlab = "mean tail length", ylab = "sample run") for (i in 1:n.draw) { if(conf.int[1,i] <= mu & conf.int[2,i] >= mu ){ #### lines(conf.int[, i], rep(i, 2), lwd = 2, col = 'green') lines(conf.int[, i], rep(i, 2), lwd = 2) } else { lines(conf.int[, i], rep(i, 2), lwd = 2, col = 'red') } } abline(v = 9, lwd = 3, col='blue') #### lty = 2, Thank you very much for your help. with many thanks abou ______________________ AbouEl-Makarim Aboueissa, PhD Professor of Statistics Department of Mathematics and Statistics University of Southern Maine [[alternative HTML version deleted]] ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
