Full_Name: Stephen Eglen Version: 1.2.3 OS: Linux (Redhat 6.1) Submission from: (NULL) (128.252.204.186) Hi, two small typos in `?write.table' (R 1.2.3) In the doc of the append parameter: append: logical. If true, the output is appended to targshe file. that should be "... to the file". and in the Details section, a full-stop is missing after names: Normally there is no

Dear useRs, When plotting with image(), I would like the z-values that extend beyond the upper zlim to be indicated with one colour, or preferably with som sort of hatching, as I'm printing in black and white. By default these values just show up as blank areas in the image. I've tried all sorts of things, but nothing seems to work for me. Any solutions would be greatly appreciated.

Small suggestion for the documentation: Should the = operator for assignments, described on http://developer.r-project.org/equalAssign.html, now be included in the operator table in doc/manual/R-lang.texi? If so, one possibility could be after lines 1096/7: @item @code{<-} @tab Left assignment, binary @item @code{=} @tab Left assignment, binary Also, where is the best place to send

Hello, I would like to plot a wireframe of a function which is defined on the unit square using the lattice library (for trellis-like plots). The plot contains z-values of about 100 (only in the neighborhood of zero) although most of the z-values are in the range of -let's say- 0 to 10. If I evaluate this function on an equidistant grid of 25 points on the unit square the plot quality is not

Dear all, I have a quiet simple problem (shared by a collegue) but no solution at yet. The arguments I use in bbox3d or text3d do not have any effect on the graph. I need to use 'cex' and 'zlim' but It does not work. Maybe my problem could appear trivial but I have spent a lot of time on that. If you have a solution, please let me know! stephane [[alternative HTML version

I just downloaded rw1041 (the latest windows binary). Everything installed fine. When I start a new Rgui, and type "demo(graphics)", after pressing return to start, a graphics window appears. When I get to the second prompt: > opar <- c(opar, par(bg = "white")) > plot(x, ann = FALSE, type = "n") Hit <Return> to see next plot: at this

Hi, [System info: R 1.6.1 compiled from source (no args to configure) on Redhat 7.1 Linux i/386] I have some spatial statistics programs that recently (since R 1.6.1) have generated SIGSEGV. These R programs use the splancs library as well as some C code of my own for Voronoi analysis. The program has a big loop to fit various model parameters against a spatial distribution of biological

Hi list, I'm trying to limit the z axis plotted using persp3d {rgl} to a given range. I'm trying the following statement persp3d(g0,pa,D, xlim=range(g0),ylim=range(pa), zlim=range (zbounds),col="lightblue") where g0 and pa are both a range of 20 numbers from 0.05 to 1, and D is a 20 x 20 matrix with values ranging from 0 to 30000. I'm trying to set a cap on the Z

Thanks... I agree that the problem was explained in the documentation but I can't find a way to have axis() working even manipulating par("plt") or with graphics.reset = TRUE: - adding graphics.reset=TRUE does not allow axis() to be shown; - I see that par()$plt is involved but it is the not sufficient to explain why axis() works because if it is changed by hand, axes are not

Hi, I'm trying to follow the suggestions given by Deepayan Sarkar in this message: http://tolstoy.newcastle.edu.au/R/help/05/11/16135.html to plot 3-D points on a wireframe plot. The problem is that I keep getting a partly formed plot- with the colored lattice visible but no axis labels or additional points- with the error message "error using packet 1, 'x' and 'units'

Hello all, I’m trying to add some data points to a wireframe. X an Y axis are independent variables, Z axis is predicted probability. I’d like to add the original data points on which the predicted probabilities are based to the wireframe. I’ve followed some of the previous post on this but get stuck : ## first part yields the wireframe## setwd("C:/Temp") rnp <-

Hi, I have a vectors x and z, for example, x <- 0:20 z <- round(runif(20,1,7)) y <- 0.5 and I want to display z as an image. However if I then call image() with a vector image(x,y,t(z),zlim=c(1,7),col=heat.colors(7),xlab="Year",ylab="Action",yaxt="n",xaxs="r",yaxs="r") then I get the error Error in image.default(x, y, t(z), zlim =

Hello List! I asked this before (with no solution), but maybe this time... I'm trying to project a surface to the XY under a 3d cloud using lattice. I can project contour lines following the code for fig 13.7 in Deepayan Sarkar's "Lattice, Multivariate Data Visualization with R", but it fails when I try to "color them in" using panel.levelplot. ?utilities.3d says there

Dear expeRts, I would like to add two points to a wireframe plot. The points have (x,y,z) coordinates where z is determined to be on the wireframe [same z-value]. Now something strange happens. One point is perfectly plotted, the other isn't shown at all. It only appears if I move it upwards in z-direction by adding a positive number. So somehow it disappears in the wireframe-surface

The following commands z <- matrix(seq(0, 1, len=1000)) image(z, 1, z, zlim=c(0, 1), col=gray(1:10/10)) appear to violate the image functionality as described on the help page. As I understand it, by specifying a zlim of c(0, 1) and a colour vector of length 10, the colours should correspond to the intervals (0, 0.1), (0.1, 0.2), ..., (0.9, 1.0), this being 10 equally-spaced intervals on (0,

Hi Folks, I'm trying to get rgl.Sweave to produce plots with transparency. However, it just seems to produce opaque plots when pdf is the output type. Perhaps this is a known issue? I'll just use .png in the meantime, but wanted to see about this, as I didn't see it in the documentation (though it's possible I missed it). Thanks, Allie \documentclass{article} \title {rgl
