Dear List I am looking for a script that will calculate the Box M test to test the homogeneity of the variance/covariance matrix between two matrices. If anyone could send me the script I would appreciate it. I am aware of the scepticism about this test, where due to extreme sensitivity a p value of 0.01 is recommended. Despite this however Box's M test is the established

Is there a function available in R that implements Mojena's Upper Tail Rule or that draws a Mojena plot? I would also like to find a function that implements Duda and Hart's stopping rule. Finally with function cophenet how can I achieve a straightforward Cophenet correlation coefficient (i.e. one number for example 0.876) that gives the agreement between the structure of the

I have a set of data that consists of a number of biological measurements. The columns are Time that runs from 01/01/2005 to 01/5/2007, Group which has 23 levels and postcode which is nested within group. This is a balanced panel but the number of postcodes differs within groups, from 15 to 400. The rest of this data consists of a number of columns of quantitative measures, largely counts.

I have two data frames with a number of common variables that I wish to put into "long format". The first contains the variables es(Csales) [1] "terr" "Dec.02" "Jan.03" "Feb.03" "Mar.03" "Apr.03" "May.03" "Jun.03" [9] "Jul.03" "Aug.03" "Sep.03" "Oct.03"

I have found lots of good advice on this forum about stacked area charts but I?ve run into problems with the 2 recommended options: stackploy in plotrix or qplot in ggplot2. I have a many page report that will be in a 2x2 page format ?par(mfrow=c(2,2))?? and need one of the page components to be a stacked chart. I?d prefer to use stackpoly, if possible, but I?m stuck on how to do the legend in

Dear List How do you change the colour settings for the banner/silhouette plot? I am trying to produce a black and white plot of publication quality. Is there a way to set black and white plots as the default for R graphics? Any help greatly appreciated. Graham Leask Economics & Strategy Group Aston University [[alternative HTML version deleted]]

Question on graphs: The default case for drawing a graph in R, is where a little space is left on the x and y axis before the first tick i.e. even if I say xlim=c(0,1) -- there will be some space between the edge of the x-axis and where 0 is placed. If I want 0 on the edge, how do I do it in R? Area under the curve: I have a 45 degree line and a curve above or below it. Is there a way in R

Talking about Excel, you can produce excellent graphs in Excel. Yes you have to work at it, but you can get there. The problem is that they are not the default. My gut feeling is that R will make more of an impact in the presentation of graphics than any implementation in Excel. So even if a patent were granted and it made itself into a mainstream package, would it change the world or would the

Hello: I should first apologize for the very basic question, but I ought to start from somewhere [embarrassed grin]. I am using R-1.0.0 in a Windows 98 machine to plot some graphs. I tried to apply a "zoom in" in some portions of the graph using say 'par(yaxp=c(0.35,0.40,5))' but nothing happens, no error msg, no update in the active graphics device. What should be the

Hi guys, Yesterday I posted my first couple of questions (see bottom of this message) to this forum and I would like to thank you guys for all the useful feedback I got. I just would like to make some comments: 1. Exporting R graphs as vector graphics: The best answer came from Thomas Lumley <tlumley at u.washington.edu> He suggested using the RSvgDevice package. As far as I know SVG

I've tried several methods in OS X, and here's what works best for me. Save the R graphic as a PDF file. Open it with Apple's "Preview" application, and save it as a PNG file. The resulting .png file can be inserted into MS Word or PowerPoint, can be resized, and looks good on either OS X or Windows. There are other programs available for translating the pdf file to png

I apologise for starting a new thread, but we had a mail problem and I don't have the original message to refer to. Someone mentioned the new "Diamond Graphs" invented at Johns Hopkins. I haven't see the August 2003 issue of The American Statistician yet, but I _have_ read the press release. The press release is a bit of a stunner. I quote: "Who would have thought we

Does anyone know how to create a 3D Bargraph using ggplot2/qplot. I don't mean 3D as in x,y,z coordinates. Just a 2D bar graph with a 3D shaped bard. See attached excel file for an example. Before anyone asks I know that 3D looking bars don't add anything except "prettiness". http://r.789695.n4.nabble.com/file/n3713305/Example.xlsx Example.xlsx -- View this message in

Hi all, I would love to plot my data with R. I have abundance and frequency of fungal taxonomic data that should be plotted in the same graph. In Microsoft Excel is that possible but the graphic result is, as always, very poor. Is there a function that may let me plot these data in R? I have a matrix made of two columns, on is the relative abundance and the other is the relative frequency for
