'symbols' not drawing correctly in the 'y' dimension
Ah! That works. Thank you very much. I interpreted from ?symbols that with inches=F getting the units from x, it was enough to coordinate the units in y. I did not know about asp. Thanks again D

Change the first line to plot(c(0, 2), c(0, 2), asp=1) That will set the aspect ratio between the vertical and horizontal axes to be equal. ------------------------------------- David L Carlson Associate Professor of Anthropology Texas A&M University College Station, TX 77840-4352 -----Original Message----- From: r-help-bounces at r-project.org [mailto:r-help-bounces at r-project.org] On Behalf Of Dami?n Cirelli Sent: Thursday, May 9, 2013 3:58 PM To: r-help at r-project.org Subject: [R] 'symbols' not drawing correctly in the 'y' dimension Hello nice R people, I'm struggling with the following code: plot(c(0, 2), c(0, 2)) symbols(1, 1, circles=0.5, add=T, inches=F) symbols(1, 1, squares=1, add=T, inches=F) abline(v=c(0.5, 1.5), lty=2) abline(h=c(0.5, 1.5), lty=2) The a-b lines in the vertical direction coincide perfectly with the borders of both the circle and the square drawn with 'symbols'. However, the a-b lines in the horizontal direction, clearly show that the circle is larger in the y-dimension than radius 0.5; same with the square. Using 'locator', shows the "y-radius" closer to 0.56 Any ideas what could be causing this? I have tried this in 3 different machines,same result. Two are running Ubuntu with the R from the repo, one is running Slackware with R version 2.15.3 compiled from source. Any help much appreciated, Damian
