Dear all, Does anyone know how to overlay a 3d line on a wireframe plot? I would also like to be able to keep the legend that you get when using the option: drape = TRUE when using the option: shade = TRUE. In addition, I would like to know how to keep the axes while getting rid of the box, I use this: par.box = list(col = NA) to get rid of the box but that also causes the axes to disappear.

Hi all, I am trying to do a 3d plot where the x,y,z axes intersects with the origin (0,0,0) using the plot3d() funtion in the rgl package without success. I looked back at the past archives on this subject and someone suggested using djmrgl package. I searched and found it, installed it but when I try to load it I get the error ... Error in inDL(x, as.logical(local), as.logical(now), ...) :

Dear all, I am trying to read a bunch of csv files using read.table() that are named "test_xxxxxx.csv" where "xxxxxx" has no particular pattern. Is there a way of reading all the files by specifying a truncated file name e.g. "test_" with some wild card characters, or would I have to laboriously create some vector with the "xxxxxx" names and iterate or

To represent a turtle inside a canvas (tcltk package), I have a serie of bitmaps representing the turtle heading in different directions and I would like to display the one that corresponds to the current direction of the turtle (function below). I have created with Paint a bitmap representing the turtle in BMP format and succeeded displaying it on canvas after converting it into XBM format

I am experiencing some problems with the windows graphics device and bitmaps. (Everything is done in R 2.3.1 on Windows XP) As an example, I will use windows(3,2) plot(1:10) It is not a pretty or meaningful graph, but it demonstrates the problem. savePlot(file="test",type="bmp") creates a bitmap file of size 303x207 which is somewhat strange because it seems to use slightly

I have two questions - 1. I am trying to create R png graphs via cron. I have this part working using Xvfb (X virtual frame buffer). One problem that I have, though, is that all the fonts on my graphs get messed up. Anybody have any nija R commands to make all fonts look great? Anybody have any idea how to fix this? So far, no luck on Solaris or Linux making the Xvfb fonts look good. I was

Dear all, I am looking for a function that can read a simple bmp file and return me a matrix with their corresponding values. I have already looked in the packages require(ReadImages) require(pixmap) and also did apropos("image") but I could not find something that can do something like that. I have also tried the read.ftable but it also failed. B.R Alex [[alternative HTML

I have some data that I need to view in various 3-D clouds. To better see the cloud structure on a 2-D screen I would like to output a bunch of bmp files with clouds at slightly different angles, then run them through an external program to animate them. But I'm having trouble getting cloud() from the lattice package to output to bmp files. Oddly, this is only a problem when outputting

Hi, is there a way to create one image file (like using win.metafile(), bmp(), etc) that contained multiple pages of plots, just like what postscript() does in creating PDF file? Thanks John

I implemented Uwe's R-WinEdt package as a closer to true WinEdt mode so that WinEdt could be used with other modes as well. I sent Uwe the implementation and we talked a little about cleaning it up, but I haven't gotten around to it and I don't think he has either. It is still a little messy as Uwe noted below but it works well. There is no code changes, just running a WinEdt macro
