[R] Problem having tick marks aligned when plotting three graphs on top of one another.
R 2.10 Windows 7 I am trying to plot three graphs on top of each other. I need to have the axises perfectly aligned. For some reason the ticks on the y axes are slightly off so they do not perfectly align. Can someone tell me how I can get the to overlay each other perfectly? I thought the yaxp parameter would solve my problem, but it does not. My data and code follows:> summaryresults[1:20,]Slope PctCont PctCat PctTTst [1,] 0.05 7.4 5.6 6.3 [2,] 0.10 17.7 11.3 13.3 [3,] 0.15 32.7 18.7 25.6 [4,] 0.20 53.3 27.5 40.2 [5,] 0.25 72.1 41.2 54.5 [6,] 0.30 85.5 52.9 70.8 [7,] 0.35 93.9 65.2 83.6 [8,] 0.40 97.0 73.6 89.9 [9,] 0.45 99.7 84.8 96.5 [10,] 0.50 99.9 90.1 98.4 [11,] 0.55 100.0 93.2 99.7 [12,] 0.60 100.0 97.3 99.8 [13,] 0.65 100.0 98.8 100.0 [14,] 0.70 100.0 99.4 100.0 [15,] 0.75 100.0 99.8 100.0 [16,] 0.80 100.0 99.7 100.0 [17,] 0.85 100.0 100.0 100.0 [18,] 0.90 100.0 100.0 100.0 [19,] 0.95 100.0 100.0 100.0 [20,] 1.00 100.0 100.0 100.0> plot(summaryresults[,"Slope"],summaryresults[,"PctCont"],type="b",yaxp=c(0,100,10)) > par(new=TRUE) > plot(summaryresults[,"Slope"],summaryresults[,"PctCat"],type="b",yaxp=c(0,100,10)) > par(new=TRUE) > plot(summaryresults[,"Slope"],summaryresults[,"PctTTst"],type="b",yaxp=c(0,100,10))John David Sorkin M.D., Ph.D. Chief, Biostatistics and Informatics University of Maryland School of Medicine Division of Gerontology Baltimore VA Medical Center 10 North Greene Street GRECC (BT/18/GR) Baltimore, MD 21201-1524 (Phone) 410-605-7119 (Fax) 410-605-7913 (Please call phone number above prior to faxing) Confidentiality Statement: This email message, including any attachments, is for th...{{dropped:6}}

John,
you need ylim for that capability.

[R] Problem having tick marks aligned when plotting three graphs on top of one another.
Hi Dr. Sorkin, One way of doing what you want is via matplot(): with(d, matplot(Slope, d[, -1], type = 'l', lty = 1)) where "d" is your data.
