Hello, I am trying to wrap my head around the coordinates systems associated with the layout() function ...with the end goal of simply drawing a decorative line in the upper margin of my figure, which is composed of three plots.
My output is defined as this: ---------------------------------------------------------------------------- postscript("out.ps", horizontal=FALSE, +width=7.5,height=11.5,pointsize=10, paper = "special" ) opar <- par(omi=c(0.1,0.1,0.1,0.1)) layout_mat = matrix(c(1,2,3),nrow=3,ncol=1,byrow=TRUE) my_layout <- layout(layout_mat,widths=c(1,1,1),heights=c(1,1.5,1.5),respect=FALSE) ----------------------------------------------------------------------------- 2 Questions: How do i find what are the x,y's of the upper margin ? (I've heard of locator() but i don't think i can use it here as i have an output file) And, also, am i allowed to draw lines using segments() or lines() in the margin regions -- defined by omi, oma -- of my figure, or are those functions confined to plot regions ? Thank You a lot, maria ______________________________________________ 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.
