How to calculate sorensen (bray-curtis) distance by dist function within the vegan package? Cheers Duccio

Hi, I'd like to know if it is possible to use Hershey vector fonts to create very primitive musical notation. If I can hang some whole notes on these lines X11() plot(0,0, xlim=c(0,10), ylim=c(0,10)) # Staves: for (i in c(seq(from=2,to=2.8,by=0.2),seq(from=4,to=4.8,by=0.2))) { abline(h=i) } it is enough. Best wishes, Atte Tenkanen University of Turku, Finland

Hello, I would like to know if (as the usa map with Splus), it is possible with R to plot the french map and to add points (representing towns for instance) on the figure in the appropriate (x,y) system. Thank you. Nathalie Peyrard

Hi, I have searched the lists but still can not solve the problem. I am using a windows machine. After I sweave some Rnw file, I got a tex file. However, the tex file can not be compiled. I know the problem is in the line \usepackage{C:/PROGRA~1/R/R-25~1.1/share/texmf/Sweave} and I need to modify this line to \usepackage{Sweave}. I hope there can be some automatic way to do this instead of

Hi all, suppose there is a vector y with rownames: > y cond1 cond2 cond3 cond4 78.952 87.308 86.490 74.040 how can I easily plot this vector using the rownames? plot(y) gives me a plot with a x-axis from 1 to 4 in 0.5 steps, also plot(rownames(y), y) and plot(y ~ rownames(y) don't work. I know I can build a x-axis with axis(1, ...), but in this case I need a character string like

Hi, I'm trying to use the "usr" argument but I see no effect of this option on my plots. For example: > par(usr=c(0,4,0,4)) > plot(1,1) This plots one point fine, but the coordinates of the plotting region are not those that I specified using par()... I can check this with > par("usr") [1] 0.568 1.432 0.568 1.432 What can I change in order to have this

Hi, I am looking for some code for Moran's I. Has anyone previously done this? I have been unable to find it in the search engines. James

I want to do "moran's I test" in R language. I try to use "gearymoran" in Package "ade4","moran" in Package "spdep", and Moran.I in Package "ape". But I do not know how to do it because data format is different. My data: x y dbh 111.03 10.7 7 118.11 0.28 1.2 165.36 0.36 8.4

Hi, I want to make a plot with abline where the area below or above the curve is shaded. I can't find any documentation on that. Can anybody help me with that? thanks, Juffi

Has anyone got vim to have syntax highlighting with R function codes? I know there's something similar that works with emacs (ESS or something like that), but I was wondering if anyone knew an equivalent that worked with vim.

Hi all I'm using Sweave and find it a treat. But one question: I use Sweave to create my pictures which are automatically included into LaTeX. For example, in the file test.Snw, I may have: % LaTeX stuff \begin{figure} <<fig=true,width=5,height=5>>= x1 <- seq(1,5, length=10) x2 <- sin(x1) plot(x1,x2) @ \caption{Plot} \end{figure} % More LaTeX This produces the LaTeX

Hi I'd like to use R in epidemiology and disease surveillance. In EpiInfo you can have a script (.pgm) which calls a predefined report (.rpt), where a table is calculated and values picked from that table and placed where the author of the report wants them, with text around those values. (Please see example below.) I've looked at manuals, faq, mail-search and google. The closest is an

how to calculate moran's i having a matrix of species vs. plots? cheers duccio

Hello- I am using the vegan package PCMN() because I need to use option of row weights (I am using CCA following the selection of the significant/positive PCNM variables). In the library PCNM (PCNM function), the Moran's I is calculated for you as part of the function. I see that I need to calculate Moran's I separately in order to retain the eigenfunctions with positive spatial

Hi- I would like to assign distance classes (lags) to the moran''s I test in R. I don¹t have equally spaced points since I was mapping shrubs across a landscape (vs. an experiment or survey in a grid). I somehow need to select points based on the distances in the distance matrix (i.e., I need to select all pairs of points that occur 0-25 m from each other, 25-50 m, etc...). Does

Dear all, I would like to calculate a Moran's I statistic using the moran function in the spdep package. The problem I'm having deals with how to create the listw object. My data stems from the area of social network analysis. I have list of poeple and for each pair of them I have a measure of their relationship strength. So my dataset looks like: Jim; Bob; 0.5 This measure of

Dear R experts, I am new to the list and R software. I need to convert arcview file to Winbugs having R has middle package. Got from friends that it is possible following the steps: 1. Converting arcview shapefile to "cgm clear text file" 2. Downloading "convert.r" to into R 2.1 use source("convert.r") 2.2 convert("filename_cgm") without the

Hi, Does anyone know how to manually configure the number of digits printed out from xtable()? For example, I'm exporting a data frame through xtable() into a LaTeX table, I only have two columns in the data frame so by default I only get two decimal places. But I'd like at least 5 decimal places. I had a look at ?xtable() but can't seem to find an example. Cheers, Kevin

hi,friends, we all know that moran's I index and Geary'C index can be used to test spatial autocorrelation in both the area data and point data, but i only can find something on how to calculate on the data of area, and can't find the methods to perform it on the point data, could anybody give me some information, thanks in advance! -- Kind Regards, Zhi Jie,Zhang ,PHD Department of
