Try this: > par(xpd=FALSE) > plot(1:10) > abline(h=4) > par(xpd=NA) > abline(h=5) the first horizontal line, at y=4, should only be visible in the box of the plot. The second line, at y=5, should go right across the graphics window. We say the first line is 'clipped' to the box. so, to draw some things outside the box you have to set par(xpd=NA) first. Its not necessary with things like mtext and axis because they obviously are going to draw outside the box anyway. It's just for points, lines, symbols, arrows etc. Barry ______________________________________________ R-help@r-project.org mailing list 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.
