Dear R People: In case anyone is interested, here are some of the answers I received regarding tick marks: plot(0,0) axis(1, pos=0) axis(2, pos=0) O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

Hi, all. Layout seems to put tick marks only in the leftmost column (for the y axis) and bottom row (for the x axis). This is easy to see using the following trivial program: function (nr, nc) { layout(matrix(1:(nr * nc), nr, nc)) for (i in 1:(nr * nc)) { plot(rnorm(10), rnorm(10)) } layout(matrix(1, 1, 1)) } I'd like to be able to override this behavior and

Hi ! I need a plot for data extending over several orders of magnitude on the y axis. The following command generates a nice looking semi-log plot for my data: plot(x,y,log="y",type="l",lty=3, ylim=c(0.01,2),yaxp=c(0.01,1,1),las=1) I would appreciate having also minor tick marks in-between the 3 major ticks obtained with the above command. The "minor.tick" function

Hi, I am unable to get the tick marks to appear thicker in plot. I have tried things like par(lw=2) but this only seems to affect other line thicknesses. The use of axes directly fixes the problem because lw = 2 applies to both the axis and the ticks. Is there is way of feeding a single parameter to plot or setting a par parameter to do this? I am using R 1.9.0 on a windows 2000 platform.

I've been trying to figure out a parameter that will let you separately adjust the parameters for the axis line from the tick mark. In the following example, I would like to suppress the axis line, but keep the tick marks. Thanks, Andrew foo <- data.frame(x=1:3, y=4:6) plot(foo$x, foo$y, type="n", axes=F) points(foo$x, foo$y) axis(side=1, at=foo$x, lty=0) #would like to figure

Dear R-help list, I have a problem with the tick marks of a Kaplan-Meier survival plot. Here is a sample: follow.up<-c(10,20,30,40,50,60,70,80,90,100) #months dead<-c(1,1,1,0,1,1,0,0,0,0) KM <-survfit(Surv(follow.up, dead)) plot(KM) The result is a nice plot. However, our research group thinks it may be a better idea to place the ticks to the years on the time scale, i.e. 0, 12, 24, 36

Hi Folks, I'm advising someone who's a beginner with R, and therefore wants the simplest answer possible. The issue is to produce a plot using plot(x,y,...) where, on the X-axis, the tick-marks should be on the lines of: -- Range of X-axis: 0:1000 -- tick-marks labelled "0","200",...,"800","1000" -- unlabelled tick-marks every 50 from 0 to

Hello list, Thank you very much for replying to my earlier questions. I have a few new questions about R plots: Example: tempdata: RDate Price 2009-12-09 12:00 100 2009-12-09 15:00 99 2009-12-09 18:00 102 .... 2009-12-10 8:00 120 2009-12-10 10:00 110 2009-12-10 16:00 105 My code: (RDate already in R date-time class) plot (price~RDate, data=tempdata, "l") axis.POSIXct(1,

Hi! Probably a simple question, but I can't get any tick marks in the 3d scatterplot I created using the cloud function. The following works to display the three groups using different symbols: data(iris) cloud(Sepal.Length ~ Petal.Length * Petal.Width, data = iris, cex = 1.2, groups = Species, pch = c(16,1,1), col = c("black","black","red"), subpanel =

Dear R People: I am drawing graphs for a College Algebra class. I would like to have the x and y axes, along with the lines that I am plotting. So I leave off the axes, and use xlim and ylim. Then I add my abline(v=0). However, I would like to have tick marks on the abline. How would I do that, please? Thanks in advance! Sincerely, Erin M. Hodgess, Ph.D. Associate Professor Department of

Hello, I have been a long-time Traditional graphics user and now moving to try Lattice graphics. At the moment I cannot figure out how to place minor tick marks in a figure made with Lattice's xyplot(). In Traditional graphics, after calling plot() I would make two calls to axis(). >From the manuals and help documentation I learned that 'scales' takes multiple 'at'

On some systems (alpha), tick marks don't appear on plots. The easiest way to see the problem is something like: > plot(0:1,axes=FALSE) > axis(1,1:2) The problem is in X11_Line(...) from .../src/unix/devX11.c, which is so short I've included the whole function below: static void X11_Line(double x1, double y1, double x2, double y2, int coords, DevDesc *dd) {

Hi all, I am trying to remove the current labels of the tick marks and replace them with text using xyplot within lattice right now I have tick marks at 1, 1.5, 2, 2.5, 3 I would like to transform them to say 'T1', 'T2', 'T3' thanks in advance Kathleen -- View this message in context:

I actually have several questions revolving around the generation of wireframe plots. The most pressing is that which is described by the subject line. I am trying to produce a figure with x, y, and z labels, but only tick marks on the x, and y axes. I have supplied sample code below substituting the volcano data set for my own such that you may run the code and see the results.

Dear R users, i try to produce the fold change versus fold change plot where i have the values for x and y ranging from 0.01 to 100. So i start with plot(x,y,xlim=c(0.01,100),ylim=c(0.01,100), axes=F). Then i would like both axes to have tick marks as c(0.01,0.1,1,10,100) but they should appear equidistant. How should i manage this? Thank you for your help, Alla.

Dear expeRts, how can I decrease the space between the tick marks and the corresponding labels in an splom? See here: library(lattice) U <- matrix(runif(4000), ncol = 8) splom(U, axis.text.cex = 0.2) # => space between the [small] tick labels and tick marks is/seems to be too large I checked ?panel.pairs but could not find an option for that. Cheers, Marius

Hello, I want to know how do R calculates the number of intervals between tick-marks in the y axis in a plot. I'm making a three y-axes plot and this information would help me a lot.

Hi, I have a dataset where we are trying to model the resistance of horses' lungs. One of the covariates is the administered pressure. This variable is a little odd in the sense that an increase of pressure corresponds to a "more negative value" of the covariate. A graph representing the change in resistance in function of the pressure would be helpful for the biologist. But it

Dear R people, I have the following simple bit of code to make a plot. I want to suppress tick marks on the axes of the plot. I've been trying everything I can think of to do so, but have been unsuccessful. Can you help me? If you reply, please cc me, I'm not currently subscribed to the list. Thanks in advance.
