I am new to R, so this is most likely a dumb question. I just installed the vcb package, but when I try to use a function from it (ternaryplot) I get an error message saying 'could not find function: ternaryplot'. I'm pretty confident that my script is correct, so I'm assuming that I did not properly install the package. Is there another step past downloading, and selecting 'install packages from zip file' in the...

...an 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 scatter, for instance, it works as expected. library(ade4) library(vcd) tdat <- data.frame(x=runif(20), y=rlnorm(20), z=rlnorm(20)) insetPlot <- function(data){ ternaryplot(data) } ternaryplot(tdat) add.scatter(insetPlot(tdat), posi="topleft", ratio=.2) Thanks very much, Jennifer Young Fisheries and Oceans Canada Jennifer.Young@dfo-mpo.gc.ca [[alternative HTML version deleted]]

Hi all Does someone know how can I alter the range of some variables in a 'ternaryplot' of the 'vcd' package, with the aim of make a zoom in some region of the plot?

Hi all Does someone know how can I alter the range of some variables in a 'ternaryplot' of the 'vcd' package, with the aim of make a closed visualization of some of its regions?

Dear R-Users, I'd like to have some tips about printing graph. I use the command par to print more graphs in one window:par(mfrow=c(6,1)); par(oma=c(2.5, 2.5, 2.5, 2.5)); par(mar=c(0.5,4, 0.5, 0.5)) But this command doesn't run with complex graphic command (i.e. xyplot, ternaryplot).How can I print more than one graph per page, when I work with this "elaborated" graph?Many thanks!Francesco [[alternative HTML version deleted]]

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, 551.22,...

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, Southampton European Way, Southampton SO14 3ZH, UK tel 023-8059-7743

Hola, Estoy buscando una representación gráfica similar a la que da: ternatyplot del paquete vcd : data(Lifeboats) attach(Lifeboats) ternaryplot( Lifeboats[,4:6], pch = ifelse(side=="Port", 1, 19), col = ifelse(side=="Port", "red", "blue"), id = ifelse(men/total > 0.1, as.character(boat), NA), main = "Lifeboats on Titanic" ) Pero con mas de 3 etiquetas, hasta 8. ¿ Conocéis a...

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)?

Dear R users, has anybody made an attempt to create the soil texture triangle graph in R? For an example see here: http://www.teachingkate.org/images/soiltria.gif I would like to get the lines in black and texture labels in gray to allow for plotting my texture results on top. Any examples or suggestions are very welcome! Thanks in advance, Sander. --

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

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? (Description...

Of course, these diagrams, by design, leave out the time element entirely. (I do hope that nobody h...

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",

I'm 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

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. Cheers, Dylan

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

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
