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

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

I using lattice to make some plots and I want to make the y-axis on some of these plots use a log scale. In the following plot: x <- 1:10 y <- 2^x xyplot(log10(y) ~ x) I get tick marks on the y-axis at 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. I would rather have just 3 tick marks at 1.0, 2.0, and 3.0 but labeled 10, 100, and 1000. I know this can be done using the "at" and

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

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: ----------------------------

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
