Greetings, R Aficionados: I'm running R2.6.2 on a DELL WinXP box with 2 Gig RAM. My package GDD renderings of dashed lines aren't dashed. abline() will produce a dashed line, but lines() won't. Here is some illustrative code: library(GDD) GDD("dashed line", type="gif", width=480, height=480) par(mar = c(4.5, 5, 2.5, 1) + 0.1) plot(x=1:10, y=1:10, pch=16, las=1) abline(a=0, b=1, lty=2) lines(x=seq(1,10, length=2), y=1+seq(1,10, length=2), col="red", lty=2) dev.off() I experimented with the lines() length parameter thinking that perhaps having too many line segments was the problem, but even with length=2 the lines are not dashed. Any suggestions? Charles Annis, P.E. Charles.Annis@StatisticalEngineering.com phone: 561-352-9699 eFax: 614-455-3265 http://www.StatisticalEngineering.com [[alternative HTML version deleted]]
