Dear List, I have been unable fo find the package quadplot3d referred in the Abstract/Presentation "Four Dimensional Barycentric Plot in 3D" presented in the UserR!2006. Does anyone know if it is available ? And if so, if it is ported to Windows ? Thanks in anticipation, Carlos Ortega [[alternative HTML version deleted]]

So I'm trying to track an special value in IPA instruction generation. https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/codegen/nv50_ir_emit_gm107.cpp#L2561 Register on 0x14 (20) is set to some source on "insn->op == OP_PINTERP" I have found while emulation that such value can be set sometimes to FragCoord.w, I don't however know what that value is and

Hello, I have a x,y,z file.Z is not corresponding to a simple analytical function of x and y (see below). I am trying to find the minimum location of this surface and the z value corresponding to this location by a spline interpolation or from a polynomial fit. I tried with the akima package but as the location of the point I am looking for (the minimum) is outside of the convex hull it's

I have 3 vectors: p1, p2, and p3. I would like each vector to be any possible value between 0 and 1 and p1 + p2 + p3 = 1. I want to graph these and I've thought about using scatterplot3d(). Here's what I have so far. library(scatterplot3d) p1 <- c(1,0,0,.5,.5,0,.5,.25,.25,.34,.33,.33,.8,.1,.1,.9,.05,.05) p2 <- c(0,1,0,.5,0,.5,.25,.5,.25,.33,.34,.33,.1,.8,.1,.05,.9,.05) p3 <-
