[R] high resolution images for publication
Dear all I am using R to produce ordinations library(vegan) and the plot function produced looks great on the screen but when I send it to jpg or pdf or eps the resolution is not so good. Can you tell me how to get high resolution images out of R for publication? Cheers Chris Buddenhagen, Botany Department, Charles Darwin Research Station, Santa Cruz,Galapagos.

[R] error bars on xy plots and barplots and histograms
Dear all I have yet to find code for making and showing error bars. Is there some idea that the simple presentation of confidence intervals is not good statistics? Any leads appreciated.

Re: [R] nonparametric 2way repeated-measures anova
Dear R Christoph Lehmann asked about this recently- as seen at http://finzi.psych.upenn.edu/R/Rhelp02a/archive/53191.html but the reply was not detailed. Did Christoph get a solution to this? Can anyone point me toward how to do repeated measures comparison using the the friedman test or other non-parametric test? I am trying to do something similar. Any example code would be useful. If anyone is willing to help I have example data I can provide. The variables are TT(=treatment), date, cover 7 treatments (only 5 replicates each), 6 measurements 2 months apart, %cover of treated plants Cheers Chris Buddenhagen, Botany Department, Charles Darwin Research Station, Santa Cruz,Galapagos.

[R] library (tree)- which samples belong to each terminal branch?
Dear all What I would like to know is if there is a way to know which specific samples fall within a terminal branch created by tree? The classification summarizes data, but I want to know which specific samples fall within each classification (branch in the dendrogram). Data contains site codes and multiple fields describing the characters of a single specimen of grass growing there. Each sample is an individual plant from a site, all plants are similar to each other, but may represent different species. I classified species using tree and these are labeled by site name. The classification gives me a nice separation of supposed species in terms of only 3 sites but with some sites occurring on more than one terminal branch, this obviously summarizes one or more species/sites on each branch of the dendrogram. So back to my question, how do I find out which samples fall within each branch? Cheers Chris Buddenhagen, Botany Department, Charles Darwin Research Station, Santa Cruz,Galapagos.

[R] multiple comparisons for proportions
Dear all I am still fishing for help on this theme. In Zar 1999 page 563-565 he describes a Tukey-type multiple comparison for testing among proportions. It involves comparisons of ranked proportions transformed to degrees. In the following pages there are a couple of similar comparisons. I cannot find an example of this in R. Is there such a thing?

[R] Multiple comparisons like a Chi2 or Fisher's exact test
Dear all I have an experiment where plots either have or have not regrown (in 40 plots) after receiving 12 different herbicide treatments and a control (no treatment). The data are significant with a Chi2, but to later distinguish if the differences are significant between each of the 12 treatments apart I need to do multiple Chi2 s between each. Is there a way to run those multiple Chi2 or something like them so that each comparison is done in an automated fashion between the treatments? Have I made myself clear?

[R] references in the manual to endnote and spanish versions of everything
Chris Buddenhagen, Botany Department, Charles Darwin Research Station, Santa Cruz,Galapagos. Mail: Charles Darwin Foundation, Casilla 17-01-3891 Avenida 6 de Diciembre N36-109 y Pasaje California Quito, ECUADOR Dear all 1) I have been really pleased with R as a means of doing and learning statistics. I work in a Spanish speaking country- and I wanted to pass on the benefits of R to my Spanish speaking colleagues. There are a couple of introductions to R in Spanish but I could only find Portuguese installation option, is there a Spanish version of the fullref manual or the program? 2) You can some references out of R and the help files in BibTex or LaTex or something, does anyone have the refs entered into endnote? Can you extract them into something readable by endnote?
