Dear R users, Up to now, I only used precompiled packages. As I am working on vegetation ecology, I would be interested in using a package not stored by CRAN called labdsv_0.9-1.tar.gz and developped by Dave Roberts at the National Center for Ecological Analysis and Synthesis (unfortunately I did not find any corresponding .zip file). Although I tried to follow the proposed guidelines to

Dear R users, I'd like to fit different longevities for males and females (µm vs µf below) with a Weibull interval-censored survival model. Unfortunately more than 50% of the individuals in the experiment died before their sex could be assigned. Hence I was wondering about fitting the proportion of females in the model ( "prop" below) with a likelihood function such as:

Dear R users, I'm trying to fit a parametric survival model using the survreg function with a Weibull distribution. I'm studying the time to death of individuals from different families and I would like to fit different shape parameters (ie 1/scale in R) for each of the families. I looked it up in the help pdf and on the internet, but I couldn't find anything. Would it be possible to

Hello all, I'm a new user of R and I have used the spdep package to calculate Moran's I estimates. I used the dnearneigh() function and moran.test() function and obtained what I wanted, but now I want to plot my results with the p-values. I regrouped my results for the Moran's I like >m=c(m1$e,m2$e...) #m1 contain the results of the moran.test for lag1

What you may need is to compile this package from source. It is explained in one of the R manuals (I can't remember which one though). You can also look at my "R Guide for Windows Users" at http://www.stat.auckland.ac.nz/~kwan022/rinfo.php (Section 5). I'm not sure the exact contents in the labdsv_0.9-1.tar.gz , but in general you can first unpack it with, e.g.: tar zxvf

Dear R users, I face to a nested pattern and despite the numerous examples in the help I am still confused. I sampled bugs in different habitats within sites which were within rivers themselves within different regions. The habitat correspond to different substrata (not systematically present in all sites). For rivers and sites, I have environemental variables (e.g. altitude and slope of

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 the following

I am trying to fit regression models type II with R, but it seems to me that most (all) of the linear model functions are for type I regressions. Does anyone knows whether type II regressions functions exist in R.

Please could you help me to find a package to apply a depth-constrained cluster analysis on palaeoecological data (in order to zone subfossil diagram)?

Bonjour, we wanted to fit a manova as descripted in Marieta /et al./ 2003, "convergent habitat segregation of /Aedes aegyptii/ and /Aedes albopictus/ (Diptera: /Culicidae/) in Southern Brazil and Florida", /J. Med. Entomol./, *40* (6), 785-794. They did their analysis with SAS software. We have the same kind of data with two insect species and city, habitat and season factors. We

Dear all, I'm puzzled by the definition of r-squared used by 'lm' when the model is without intercept. The help for summary says: >r.squared: R^2, the ``fraction of variance explained by the model'', > > R^2 = 1 - Sum(R[i]^2) / Sum((y[i]- y*)^2), > > where y* is the mean of y[i] if there is an intercept and > zero

Hi all, I am wondering whether there is a small bug in the binom.test function of the ctest library (I'm using R 1.6.0 on windows 2000, but Splus 2000 seems to have the same behaviour). Or perhaps I've misunderstood something. the command binom.test(11,100,p=0.1) and binom.test(9,100,p=0.1) give different p-values (see below). As 9 and 11 are equidistant from 10, the mean of the

Hi All, Sorry for asking the most repeated question again. Just because I could not get a proper guide for doing this. Can anyone please tell me how to make a linux system running samba server and client to connect ( log on to ) to a windows2000 based domain and act as a part of it ? Any useful link also would do. thanks in advance :-) senthil -------------- next part -------------- HTML

Hi, I misunderstand the definition of Canberra distance in R. On Internet and in function description pages of dist() from stats and Dist() from amap, Canberra distance between vectors x and y, d(x,y), is : d(x,y) = sum(abs(x-y)/(x+y)) But in use, through simple examples, we find that the formula is : d(x,y) = (NZ + 1)/NZ * sum(abs(x-y)/(x+y)) with NZ = nb of pairs of coordinates that are

Hi Lists, sorry for reposting this, but since no response has arrived so far and my time on this project is passing by I need to make a conclusion. Do I better use my DVR cards in dom0 or moving it to a separate physical machine rather than using them in a domU? Could someone shed light on why it is trickier to pass-thru one of these cards than any other pci devices? Do they try to read-write

Yeah, the app will probably only be for viewing statistics and other Icecast data - and not for "managing" or modifying the server since it isn't possible from the Web interface. Any suggestions for what Icecast data the app should display? On Sun, Oct 6, 2013 at 2:29 AM, Basil Mohamed Gohar < basilgohar at librevideo.org> wrote: > On 10/05/2013 04:26 PM, Elad Nava

Hi all, I am a very recent user of R. Mine is probably a basic question. I would like to know how do we create a certain set of points with geographic coordinates, between two endpoints. Please explain me how to do this using R. Which are the packages to be used for doing this. Thanks in advance, Ravichandra Mondreti. Ravichandra Mondreti PhD student/ Doctorant Spatial

Hello all, I'm a new user on R, and I used the abline function to draw a line on my graph but it doesn't work with xyplot(). With the plot function, abline() is ok but with plot it doesn't make what I want. Maybe it's a little thing to change in plot() but I don't find what! With xyplot I write this : Xyplot(m~ordered(l,levels=1),
