Hi Has anyone tried to fit a thin plate spine to a triangular plot before? I'm having trouble working out a piece of code to make it possible with three axes. I have done it before with two axes. I've found a package I prefer that makes triangular plots (plotrix) using the triax.plot() function. An example of some data and the plot follows: graph.data<-data.frame(a=c(9,6.2, 5.9,8.1,8.9,56.9,50,39.5,62.1,49.9,4.2,3,6,4.1), b=c(1.8,1.2,1.2,1.6,1.8,11.4,10,7.9,12.4,10,4.2,3,6,4.1), c=c(1.8,1.2,1.2,1.6,1.8,11.4,10,7.9,12.4,10,4...

Hi, Is anyone on the list familiar with an R implementation of Piper Diagrams? Example: http://faculty.uml.edu/nelson_eby/89.315/IMAGES/Figure%209-78.jpg I am thinking that two calls to triax.plot (plotrix) along with some kind of affine-transformed standard plot would do the trick. Not so sure about the final layout, or a nice generalized version for something like lattice.

Hello, I need to chenge axes orirentation in triangle plot. (function triangle.plot in ade4 package) I want to plot elasticities of some species in demographic triangle, where axes values commnly increace "clockwise". If some better imangination is needed, see http://www.open.ac.uk/science/biosci/personalpages/j.silvertown/pdfs/Silvertown%20et%20al.%201993.pdf I am sorry if I just

Suppose I have three numbers p1, p2, p3 with 0 <= p1,p2,p3 <= 1 and p1+p2+p3=1, and a function f=f(p1,p2,p3) = f(p1,p2,1-p1-p2). How to draw a contour plot of f() on the p1+p2+p3=1 plane, that is, an equilateral triangle? Functions triplot(), triangle.plot(), and ternaryplot() give only scatterplots, AFAICS -- Robin Hankin Uncertainty Analyst National Oceanography Centre,

I need to plot multiple sets of data, on one Ternary plot (from the VCD package). Since they all need to be formatted differently, I can't just coerce them into one matrix, I need three separate calls. Is there a way to do this?

Hi all, I am drawing a ternary graph. Everything is fine with both ternaryplot (package vcd) and triangle.plot (package ade4), but I want to present scales in neither percents nor from 0 to 1 (this is actually the only option I found in both functions). I want the scales to be in a natural scale (from 0 to k, k being the number of objects). Is it at all possible? (Descriptions of both functions

I'm not so sure the original way I stated my issue was clear enough, so I'll attempt to elaborate a little bit. I'd like to make a function that is passed the name of a plot object, and a lines/point specification, and graphs them all on the same plot. I don't want to redraw the plot each time, and I don't want the code to have any concept of a "first entry"

Hello I am trying to add a ternary plot as a corner inset graph to a larger main ternary plot. I have successfully used add.scatter in the past for different kinds of plots but It doesn't seem to work for this particular function. It overlays the old plot rather than plotting as an inset. Here is a simple version of what I'm trying. Note that if I change the inset plot to be an ordinary

Hi all, I am working on a filled contour plot which shows a triangular matrix data set (as shown below). Is there a possibilty to draw a triangular filled contour in a equilateral triangle (like a ternary plot)?

Hello, Using the dataset below I produce a soil.texture plot (R code for this included at the end). One will notice I have plotted the points based on whether or not they are in a region called 'upstream' or 'downstream'. I'm curious if there is a way to somehow extract counts of the number of points (red points and blue points) falling within each classification (e.g. silty
