Why? Your data extend to ~-0.07. > , as mentioned in > the code (cf picture) :confused: > http://www.nabble.com/file/p23742121/Rplots_2.png You didn't adjust the x-axis limits to tell R that you wanted -0.1 to be include on the lower end of the axis. R isn't clairvoyant you know! I've tidied your script and altered it to extend the x-axis a bit so that -0.1 is included: Win <- c(-0.005276404, 0.081894394, -0.073461539, 0.184371967, 0.133189670, -0.006239016, -0.063616699, 0.196754234, 0.402148743, 0.104408425, 0.036910154, 0.195227863, 0.212743723, 0.280889666, 0.300277802) Calgary<- c(5, 8, 11, 3, 7, 4, 7, 1, 3, 6, 3, 2, 8, 0, 1) data_corr <- data.frame(Win, Calgary) plot(Calgary ~ Win, data = data_corr, type = "p", axes = FALSE, col = "blue", lwd = 2, xlim = c(-0.1,0.5)) ## ^^^^^^^^^^^^^^^^^^ axis(2, tcl = 0.35, seq(1, 11, by=2)) axis(1, tcl = 0.35, seq(-0.1, 0.5, by=0.1)) box() abline(lm(Calgary ~ Win, data = data_corr)) HTH G -- %~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~%~% Dr. Gavin Simpson [t] +44 (0)20 7679 0522 ECRC, UCL Geography, [f] +44 (0)20 7679 0565 Pearson Building, [e] gavin.simpsonATNOSPAMucl.ac.uk Gower Street, London [w] http://www.ucl.ac.uk/~ucfagls/ UK.
