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

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,

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'

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

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-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

The following commands illustrate a problem with graphing relatively large data sets using the "line" option to plot: temp <- runif(200000) # or whatever other numbers you like; # same thing happens with a sine wave plot(1:200000, temp) # everything fine plot(1:200000, temp, type="l") # data gets cut off The number of points isn't crucial. The cutoff point

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:

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.

Hello, all. I've got what is probably a simple question about comparison of models using anova, specifically about the situations in which it's valid. I understand, I think, what's going on when the models are strictly nested (as most are in the demo(lm) examples). My question involves what happens when the models aren't strictly nested. In my particular case, I'm doing

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

Hello there! I'm starting with ggplot and was wondering how I could control the axis of a plot. I would like the axis of the plot to be drawn black which I thought to acheive with the option axis.colour="black". However, this had no real effect on the plot. Then I found grid.colour which I changed to black as well. Now I got my axis as I wanted them, but ggplot now draws the grid

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

I am using POSIXct objects to store my date/time information. If I am plotting less that 2 days worth of data, I get the correct tick marks on the x-axis which is showing the 'day HH:MM' and these line up with the data points. If the data spans more than 2 days, the tick marks are now off. In the data below, I am creating some sample data and plotting the points. I am in the Eastern

Hi, all. The following does not behave as I think it should, and as it seems to me it has in the past (although I can't check this easily). I know it happens in both R-0.64.2 and R-0.65.0 on an old Power Computing running Linux-PPC 1999, and in R-0.64.2 on an SGI running Irix 6.5. Try the following: t1 <- data.frame(matrix(rnorm(16), nc=4)) > t1 X1 X2 X3 X4 1 -0.7206945

Hi, I have the follow ggplot2 code I am running: ggplot(data=bb.res.math,aes(x=factor(id.bb),y=bb.math.comb,fill=BB)) + geom_bar() + facet_grid(BB~.) + scale_fill_brewer(pal="Set1") + ylab("Average Student Residual (Math)") + xlab("Student ID") The number of unique id.bb is 2207 and so my X-axis has a couple of thousands, indistinguishable tick marks that correspond
