rgl

I am trying to plot a 5 dimensional plot in R. I am currently using the rgl package to plot my data in 4 dimensions, using 3 variables as the x,y,z, coordinates, another variable as the color. I am wondering if I can add a fifth variable using this package, like for example the size or the shape of the points in the space. Here's an example of my data, and my current code: set.seed(1) df <- data.frame(replicate(4,sample(1:200,1000,rep=TRUE))) addme <- data.frame(replicate(1,sample(0:1,1000,rep=TRUE))) df <- cbind(df,addme) colnames(df) <- c("var1","var2","var3","var4","var5") require(rgl)

I have created a 3d map using rgl.surface(), mainly following Shane's answer in this post. Using my own data, I get this map On top of this surface map, I would like to add a map of vegetation density such that I obtain something like this (obtained with the software Surfer): Is it possible to do this with rgl, or for that matter any other package in r or is the only solution to have two maps like in Shane's answer? Thank you. Edit: Following @gsk3's request, here is the code for this map: library(rgl) # Read the z (i.e. elevation) dimension from file z1 = matrix(scan("myfile.txt"),nrow=256,

I just upgraded R and rgl to the following versions. Now, rgl.snapshot() no longer works. It worked in previous versions. Is there a way around this? R version 2.12.1 (2010-12-16) rgl version 0.92.798 > library(rgl) > x<-rnorm(100) > y<-rnorm(100) > z<-rnorm(100) > r<-0.2 > p <- plot3d(x, y, z, axes=FALSE, box=FALSE, radius=r, type='s', + xlab="", ylab="", zlab="", col=rainbow(100)) > rgl.snapshot("C:\\Temp\\pic.png", fmt="png", top=TRUE ) Error in rgl.snapshot("C:\\Temp\\pic.png") : pixmap save format not supported in this build That build doesn't have PNG support (yet). You can use

Whenever I do a re-plot on a RGL plot3D it causes the view orientation of the plot to be reset to it's default. Does anyone know how to save these settings so that I can reapply them after a plot is redrawn. I tried this : # save settings pp <- par3d(no.readonly=TRUE) # initialize plot plot3d(c(), c(), c(), "", "", "") # Replot data here # ... # restore settings par3d(pp) However, this did not restore the plot orientation. EDIT: printing out the result of par3d() shows that the values are not getting updated as the plot is rotated and zoomed, so I'm guessing this is the issue. It might be an

I'm trying to make some visual modifications to the default plot3d object. Specifically i would like to put a light box color as a background (only in the box, not the whole palette) and remove the axis tick marks (the x,y,z values on the axis are distracting). I have spent countless hours googling what options to change, but I cannot for the life of me figure this out. Any help would be super appreciated. I whittled down my code to the following, so that you can re-produce it. library(rgl) xvar <- c(0.23158792, 0.09686823, -0.58937138, -1.04380419,0.52169760, 1.15218492, 1.36873947, -0
