With some help from those with expertise on this list, I managed to produce a plot using trellis that looked like I wanted it to look. Now, I need to take the same plot and make the lines on it color, but I want to specify the color for the lines myself. I've managed to make the key use the colors I want. I've managed to make the symbols of the actual plot use the colors I want. But I

Hi I have patched together (from various sources) the following code to get semi-logarithmic plot. Unfortunately, my labels come out also at intermediate places between 10^2, 10^3, 10^4 etc. Since I put the code together from various sources and do not understand fully how the code is working, I have not been able to get rid of the labels like 10^1.69897, 10^2.69897 etc. I would appreciate if

If I use the following command to plot points: plot(c(1,2,2,3,3,3), type="p", pch=20, ylab="Y Label", xlab="X Label", xaxt="n") there is a large amount of space between the label "X Label" and the actual x-axis. If I change the xaxt="n" to xaxt="s", the label "X Label" don't move at all. Is there a way to get

Hi, I am trying to put on one plot two different logarithmic scales, using the bottom and top X-axes. Below there is an example of what I am trying to achieve, using axTicks() -- and fails. I already spent few hours on that, and cannot figure out from ?par and ?axTicks what I am doing wrong. Example follows: ############################################################ #### Data x <-

There is still issues with the reversed y-log scale plot: # Test case A: works as expected plot(10:100,log="y",ylim=c(100,11)) grid() par("yaxp") # Test case B: grid does not have horizontal lines; par("yaxp") is different plot(1:100,log="y",ylim=c(100,10)) grid() par("yaxp") In the second test case, axTicks for the horizontal lines (in

?axTicks says: usr: numeric vector of length four, defaulting to ?par("usr")? giving horizontal (?x?) and vertical (?y?) user coordinate limits. but this is not how the function is implemented -- in fact 'usr' should be a vector of length two corresponding to the appropriate elements of par("usr") [1:2 if side is 1 or 3, 3:4 if side is 2 or

I'm running R from an Xterm window is OSX-Tiger. Graphical windows appear as they should, but I'm having trouble copying from them--using cmd+c or the Copy option in the Edit menu won't place the graph in the clipboard (when I paste into a running OS X app, I get whatever was the last copied thing from a non-x11 window). Any ideas on how to copy from a xterm-launched graphical

Is there a function that does the same as pretty but on a log-scale? Suppose you have x <- exp( runif( 100, 0, 6 ) ) (which will between 1 and 403), then I would like to have a result like: log.pretty( x ) [1] 1 5 10 50 100 500 Bendix C. ---------------------- Bendix Carstensen Senior Statistician Steno Diabetes Center Niels Steensens Vej 2 DK-2820 Gentofte Denmark tel: +45 44 43 87 38

Dear all, I would like to (i) produce boxplot graphs with axis in logarithm in base 10 and (ii) showing the values on the axis in 10^exponent format rather than 10E+exponent. To illustrate with an example, I have some widely spread data that I chart plot using boxplot() [figure on the left]; the log="y" option of boxplot() I obtained the natural logarithm conversion of the data and

Similar to my last question, I want to tighten up the spacing and margins in a plot I am doing with lattice. Here are the commands I'm using: data <- data.frame(x=c(1:3, 1:3), y=c(1:3, 1:3*2), cat=c("foo","foo","foo","bar", "bar","bar")) xyplot(panel=panel.superpose, y~x, data=data, groups=cat, type="b",

I'm using barplot2 to plot some data. Is there any way to determine the width of the bars in the generated plot? I know that barplot2 returns a list of the coordinates of the center of each bar, but since there is some white space between each bar, I don't know how to get the width of each bar. Jamie

I have some plots that I generating using R (using trellis, plot, and barplot2) that I want to include in a PowerPoint presentation I am giving. My computer is running OS X. I find that presentations are easier to read when there is light text on a dark background and would like to generate plots that fit that style. The plots I am generating are all grayscale. Is there an easy way to get R to

I have a barplot I have created using barplot2 and I have been able to add points and lines (using the points and lines methods, respectively). I now need to add some polygons (triangles in particular), that I want to be shaded to match bars in the plot. I can get the coordinates of the corners of the triangles, but don't know how to draw the triangles. I know there is the grid.polygon

With much help from Chuck Cleland, I was able to get xyplot to generate the plot I wanted. I'm trying to write a script (that can be read using source("file")) to create the plots I want and save them to files. If I type the following lines into the R (in interactive mode), the correct plot gets saved into the file myfile.ps with a size of 4,096 bytes: ----------------------------

Hello R-experts, I am facing a strange problem while creating a barplot. I have serise of data of which the first on is around 162589 while the remaining data are around 0-150. so when I am ploting the barplot with all the data I am getting a single line -> test1.jpg. But If I remove the 1st value i.e 162589 then I am getting a normal barplot -> test2.jpg Can some one help me regarding

Hi, I was trying to run the following, where the labels on the x axis are dates and need to be converted to characters. It did not work. Any help would be appreciated. Thanks. > text(axTicks(1),par("usr)[3]-2,srt=45,adj=1,labels=as.character(c("2008-01-08","2008-08-10","2008-08-22","2008-09-03", "2008-09-15")), xpd=T, cex=0.8) Error:

Hi all, Before posting to r-bugs, I thought that I would just verify this one first. It looks like the help for axTicks() needs to be corrected. It presently says: 'axTicks()' can be regarded as an R implementation of the C function 'CreateAtVector()' in '..../src/main/graphics.c' which is called by 'axis(side,*)' when no argument 'at' is specified.

I have a data frame with three columns, type (a factor with two values: "Monolithic" and "Compositional"), size (numeric), and states (numeric). I want to create a plot where size goes on the x-axis and states goes on the y-axis. In this plot, I want two lines, one where the type is "Monolithic" and one where the type is "Compositional". I think this can

Hi all, I need help with axis in plot. I want to edit y axis label of my plot. My data is like: x <- c(100,50,10,1,0.1,0.05,0.001) plot(log(x)) axTicks(2) # Label of y axis [1] -6 -4 -2 0 2 4 I'd like that y axis label was like: e^-6, e^-4, etc. (with text "e" superscript -6, -4, etc.) I try to use expression(), but don't work. plot(log(x), yaxt="n")

I was trying to recreate this kind of timeline plot: http://www.vertex42.com/ExcelArticles/create-a-timeline.html As you can see in their excel example, the events are nicely placed out on both sides of the timeline axis. AFAIK there is no function to do this nicely in R-project. Furthermore, graphics and lattice packages are unable to draw the x-axis in the middle of the plot. (datapoints
