Colin, If your propose is to create a ternary plot with points and vectors, I think easier do this with graphics based plots instead of trellis based plots. Although, with little work you can do with trellis too. I gave you a reproducible code to put an arrow in a ternary plot. I use the function locator() to extract coordinates. The code is t...

...in e-mail contact with a geochemist who maintains a well regarded geochemistry web site. He's drawing diagrams either with a Turbo Pascal program running in a DOS window or with Excel. I'm trying to persuade him that R would be a better choice. Something he's particularly keen on is ternary diagrams. I think he is talking about ternary phase diagrams, and if so, it looks as though it should be doable in R, but I don't know enough about the lower levels of R graphics to do it myself (yet). Looking at his speed and volume requirements, R can handle them easily, even on a machine a...

Hello Jochen- Your expectation is incorrect, I'm afraid. Typically this would be expanded to something like this: … %cmp = … br i1 %cmp, label %ternary.true, label %ternary.false ternary.true: %truevalue = … br label %ternary.end ternary.false: %falsevalue = … br label %ternary.end ternary.end: %value = phi %type [%truevalue, %ternary.true], [%falsevalue, %ternary.false] This may then be optimised to a select by later passes, if it...

Hi, I am trying to create a triangular plot to show the 'composition' of a set of items with three variables (historically the percent sand, silt and clay in soil). So far I have tried the 'soil texture triangle plot' in the package plotrix and the 'ternary or triangular plots' in the package cwhtool (cwhmisc). Both have strengths and weaknesses, but neither has a 'standard' or 'generic' feel about it. To save myself time I would like to ask the list if there is a preferred or standard implementation of the triangle plot that...

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...

Dear R-Users, I'd like to have some tips for a ternaryplot ("vcd"). I have this dataframe: a<- c (0.1, 0.5, 0.5, 0.6, 0.2, 0, 0, 0.004166667, 0.45) b<- c (0.75,0.5,0,0.1,0.2,0.951612903,0.918103448,0.7875,0.45) c<- c (0.15,0,0.5,0.3,0.6,0.048387097,0.081896552,0.208333333,0.1) d<- c (500,2324.90,2551.44,1244.50, 551...

Hello I have a data base consisting of soil parameters, and tree species densities. The vcd (visualizing categorical data) package includes the ternaryplot function which plots the gravitation center of 3 prameters. I'd like to find a similar function for use with continuous data rather than categorical. Does anyone know of a function suitable for this objective? Thanks Steve Friedman

A rather strange situation here and I've not found the source of the problem. The point is to print a ternary plot matrix of compositional data with ellipses enclosing 95% of the variance in each plot. The ellipses display on the monitor, dev = x11cairo (see attached winters-x11cairo.pdf), but not when sent directly to a file, dev = pdf (see attached winters-pdf.pdf). Here's winters.acomp: structu...

...hether some points lye inside, outside, on the border or on a vertice of a polygon. I have a list of point I know should lye right on the border of a polygon, but some of them are not classified as such by point.in.polygon() (see the example code below). To make a long story short I am working on ternary variables that sum to 100% (soil texture data), that can be plotted on a ternary diagram (soil texture diagram) & classified according to subdivisions of the diagram (soil texture class). For a given data point, when one or more of the the 3 variable is equal to 0, and when their sum is 100%, I...

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'...

I find myself doing the following quite a lot: <% if user %><%= user.name %><% else %>Anonymous<% end %> I know that if I dont care about an else I can just do: <%= user.name if user %> Is there any simpler way to handle the else? This is a simple example so it''s not really an issue.. but for more complicated tests this gets quite tedious. -- Posted

I have two vectors (k.floor and k.ceiling) of integers of the same length, and a function (fpr). b <- 10:40 k.floor <- floor(log(2) * b) k.ceiling <- ceiling(log(2) * b) fpr.floor <- fpr(b, k.floor) fpr.ceiling <- fpr(b, k.ceiling) If R had a element-wise ternary function, I'd like to do something like this: (fpr.floor < fpr.ceiling) ? k.floor : k.ceiling That is, I'd like to go through the two vectors in parallel, picking the one that returns the lower value of fpr. Failing to find such a function, I wrote the following two lines: in...

...> Oh, I see. So you're worried that an FNeg won't match the generic m_c_BinOp(...) as it does now. That's a reasonable concern. This is the first time I'm looking at foldShuffledBinop(...), so maybe a naive question, but why not do similar shuffle canonicalizations on unary (or ternary) operations? That may be a better fix in the long run. > But glancing at Reassociate.cpp is scarier.

...if the result is a legal type. But actually we want to continue and promote the elements of the vector. In other cases we may want to widen (to the next power of two) and later split in half because the vector is too big. Thanks for the tip. I modified WidenVecRes_Binary match WidenVecRes_{Unary/Ternary} and it does the promotion and generates much better code. Why is WidenVecRes_Binary so much more complicated than the Unary/Binary functions? None of the operations in the cases for WidenVecRes_Binary seem any more special then the operations that use WidenVecRes_Unary.. paul On Aug 12, 2013, a...

Hello, I have three x-y plots whose interesting data occurs at the same time. When I place them in the same plot, they tend to obscure each other. I was hoping to use persp or scatterplot3d to plot them 3-dimensionally, so that the plot is visually useful. My data is simple: x, for all three data sets, is a set of 885 ISOdates, where x <- x0 + seq(1, 885). y is the value of "io",
