Hi First, sorry if I get the terminology wrong, I am still quite new to the concept of using environments and workspaces. Say I have a statement in a package SIM like sim <- TYPE where the variable TYPE is initialized in the package to e.g. "exponential" (SIM::TYPE == "exponential"). Now, I want to give the user the option of specifying the variable TYPE, but to the

Hi R users, Does anyone know how to change the size of 3d charts? I'm using surface3d in rgl package, opening a new window each time to display the chart. I want it so that the chart fills the whole window, because when I output it to png, I don't want all the white space around the chart (right now, i'm getting this white "border" around the chart because the chart is

...elping me handling key down. How do I say in a custom mouse handler "after having done your work, forward to standard trackball once only"? The example below shows the idea, but it works only once, then reverts to standard trackball handling. Dieter #---------------------- library(rgl) r3dDefaults open3d() shade3d(cube3d(color=rep(rainbow(6),rep(4,6)))) btn3d <- function() { begin <- function(x, y) { # Add checking for key down later cat(x,y,"\n") # Forward to trackball (no easier way?) newhandler <- par3d("mouseMode") newhandler[1] <-...

Hi there, I've written a script for reading 3D simulation data into R, rendering it using RGL, and then saving the resulting plot using the snapshot3d() function. The results are fantastic! However, whenever RGL plots anything it automatically brings the viewing window into focus. Since I'm producing a large number of plots in a loop, my machine becomes almost unusable for the

I'm writing a book using Sweave which includes Unicode characters which R's postscript and pdf graphics devices don't handle properly. The cairo graphics device does handle these characters properly. Thus I'd like to be able to instruct Sweave to use cairo (either sometimes or always) to produce graphics when it processes R code. Is this possible? Many thanks, Roger Levy --

Dear all, The documentation on the function open3d in the rgl package, reads: open3d opens a new rgl device, and sets the parameters as requested. I want the new rgl device (window) to be sized and positioned in a specific place on my screen. So, I try to set the "windowRect" parameter as follows: > library("rgl") > open3d(windowRect=c(100,100,500,500))

I have been making simple functions to display regressions in a new package called "rockchalk". For 3d illustrations, my functions use persp, and I've grown to like working with it. As an example of the kind of things I like to do, you might consult my lecture on multicollinearity, which is by far the most detailed illustration I've prepared.
