This looks more like a problem of pdf than one of image. Under Windows and current R, I cannot reproduce the line in the pdf, but we have seen this before. If you are sure that you have the current version of R installed, you could send in a bug report, but make sure sessionInfo() is included. One workaround that worked for me in the past to use a CairoPDF as show below. Dieter library(Cairo) CairoPDF(file="c:/tmp/Hello.pdf") x <- 0:20 y <- 0.5 z <- round(runif(21,1,7)) z <- matrix(c(z,z),2,length(z),byrow=TRUE) y <- c(0.25,0.75) image(x,y,t(z),zlim=c(1,7),col=heat.colors(7),xlab="Year",ylab="Action", yaxt="n",xaxs="r",yaxs="r") dev.off() -- View this message in context: http://r.789695.n4.nabble.com/image-with-a-vector-tp3308265p3308283.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ 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.
