rgl

I'm trying to install the R package rgl on Ubuntu 9.10. I'm using R version 2.12.1. I got the following error: "configure: error: missing required header GL/gl.h" Edit: My original question did not specify that the operating system must be Ubuntu 9.10. I gather that otherwise it would be a good idea to update R, but that this cannot be done on Ubuntu 9.10. Because I'm stupid, I posted a new question instead of editing this one, so some discussion has occurred there. I had to deal with this problem many times, and this always worked just fine: type in a terminal sudo apt-get install libglu1

I'm trying to simulate some data (x1 and x2 - my explanatory variables), calculate y using a specified function + random noise and plot the resulting observations AND the true regression surface. Here's what I have so far: set.seed(1) library(rgl) # Simulate some data x1 <- runif(50) x2 <- runif(50) y <- sin(x1)*x2+x1*x2 + rnorm(50, sd=0.3) # 3D scatterplot of observations plot3d(x1,x2,y, type="p", col="red", xlab="X1", ylab="X2", zlab="Y", site=5, lwd=15) Now I'm not sure how I can add the "true" regression plane. I'm basically looking for something like curve() where I can plug in my (true)

In the world of the R statistics package, rgl allows me to generate 3d plots that I can rotate with my mouse. Is there a way I can export these plots in a portable format, load them in a web browser or other third party tool and rotate them there? I Am especially interested in the web browser solution since this will allow me to share the plots on an internal wiki. If rgl does not allow this, are there other libraries or strategies that would allow me to accomplish this? You could try the vrmlgen package. It will produce 3d VRML files that can be displayed with a browser plugin; you can find a

The curve function in R provides a simple way to plot a function. For example, this will plot a straight line f1 <- function(x) x curve(f1, from=-1, to=1) Is there an equivalent function in R which takes a function with two argument (e.g., x and y ) and ranges for both variables and produces a 3D plot? For example, imagine I had the following function f2 <- function(x, y) x + y Is there a command similar to the following? curve_3d(f2, x_range=c(-1, 1), y_range=c(-1, 1)) The surface3d function in package:rgl looks like a good match. It would be very simple to create a wrapper that would take

I am trying to install rgl package (0.92.858) for R (2.14.2) under Mac OS X (Lion 10.7.3). When I try to load it (library(rgl)), I get the following error: Error : .onLoad failed in loadNamespace() for 'rgl', details: call: dyn.load(file, DLLpath = DLLpath, ...) error: unable to load shared object '/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so': dlopen(/Library/Frameworks/R.framework/Versions/2.14/Resources/library/rgl/libs/x86_64/aglrgl.so, 6): Symbol not found: __ZN3gui13OSXGUIFactory12hasEventLoopEv Referenced from: /Library/Frameworks/R.framework

Using knitr it is possible to embed a rgl 3D graphics in a html document from a Rmarkdown source file: ```{r setup} library(rgl) knit_hooks$set(rgl = hook_rgl) x <- sort(rnorm(1000)) y <- rnorm(1000) z <- rnorm(1000) + atan2(x,y) ``` ```{r, rgl=TRUE} plot3d(x, y, z, col=rainbow(1000)) ``` But the 3D graphic is not interactive in the html document. Is it possible to get an interactive 3D graphic ? The writeWebGL() function of the rgl package creates a html file with an interactive 3D graphic, is there a way to include directly this html code with Rmarkdown ? Otherwise how to include this html
