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

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 =

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

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

Dear all, I'm trying to improve the default layout of tick marks for log scaled axes in ggplot2. To this end, it would be really useful to see what people actually do in practice. If you've ever made a log-log (or semi-log) plot and customised the location of the ticks, I'd really appreciate a copy of your graph (if it's publicly available) or a statement of the range of the

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.

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.

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,

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, 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.

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. Sincerely, Faheem Mitha. num <- 1:i inc

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 very much appreciate any help on this "fine tuning" problem in a lattice graph (I am new to LATTICE and could not find an example in the help files that worked for me. My apologies if I missed it there). I am running the following box plots to compare conditional distributions of x at different levels of y under two treatment conditions ID=1 (upper panel ) & ID=0 (lower panel

Hello, I think I found a bug: > windows(1,width = 10, height = 10, pointsize = 5,xpos = 0, ypos = 0 ) > hdata[1:3,1] <- c(1,10,15) > hdata[1:3,2] <- c(2,1,4) > plot(hdata[,1],hdata[,2],xaxt="n") > axis(1,at=c(2,10,14)) > minor.tick(nx=2, ny=1,tick.ratio=1) the minor tick marks appear between the tick marks which would have been drawn without the option

For example, this works: x = seq(-100, 1000, 25) y = x * x plot(x,y, xaxt="n") axis(1,x,FALSE,tcl=-0.3) axis(1,x[x %% 100 ==0]) It creates two axis objects and the values of the x-axis are the labels. The following scenario is more difficult, because it uses 'image' to plot a grid of values: a = matrix(rnorm(100),ncol=10) image(1:ncol(a), 1:nrow(a), a, xaxt="n",

I am trying to plot some data, but have got some difficulties with labels on the tick marks on the x-axes. There are 20 data points. All I want to do is to plot the Loss versus Lines. When I use xyplot, the first tick mark starts from 2 rather than 1, and also there is a NA as the final tick mark. Here is the R code you code give it a try: Would any body be able to fix this, please?

Sorry, I have read other posts on tick marks but nothing is working. Here is my R code. I was able to turn off the x axis at one point (I removed that code), but never got the tick marks on by 20s. It always goes to the default of 50, 100, 150, 200. Thanks. R code: hist(OMY$FL, main = "2010 Oncorhynchus mykiss Fork Length Frequencies at Buck Creek Reach 1", include.lowest = TRUE,

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:
