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)) [1] 1 Obviously you can't see where the window appears, so I'll ask for the "windowRect" parameter: > par3d()["windowRect"] $windowRect [1]...

Hello, Using the rgl package, I can set the device window to any dimension (that I have tested): par3d(windowRect=c(1,1,700,700)) With windows I can't get the window to span from the top to the bottom of the monitor. In the following, no matter how large the ypinch value gets it stops, leaving about 2 inches of space at the bottom of my screen: windows(record=TRUE, ypinch=1100, xpinch=10, xpos=1,ypos=1, r...

Hi, I try to execute the seven lines of code below to plot a graph. But I am failing as the messages below show. Where am I going wrong? install.packages("rgl") library(rgl) y_hat = X%*%B_hat open3d(windowRect = c(100,100,900,900),family = "serif") color = rainbow(length(y_hat))[rank(y_hat)] plot3d(educ,exper,wage,col = color,type = "s",size = 0.5,xlim = c(0,20),ylim = c(0,60),zlim = c(-10,70),box = FALSE,axes = TRUE) planes3d(B_hat[2],B_hat[3],-1,B_hat[1],alpha = 0.5,col = "azur...

Hello everyone, I know I can save a snapshot an rgl device, but currently it only appears to do png format. Is there some way of exporting a high-quality picture more fit for publication? Thanks, Mike

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

...ackage VecStatGraphs3D. My question is: if we use more layers than one, could we change the function in a way that in the final plot only the outmost layer is drawn (the inner layers omitted)? Best regards, Atte Tenkanen function (vectors, Div = 40, Layers = 3, DrawAxes = FALSE) { open3d(windowRect = c(100, 100, 800, 800)) bg3d("white") Cx = vectors[, 1] Cy = vectors[, 2] Cz = vectors[, 3] Cr <- kde3d(x = Cx, y = Cy, z = Cz, n = Div) th <- seq(min(Cr$d), max(Cr$d), len = Layers + 2) ramp <- colorRamp(c("white", "yellow"...

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 --

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.
