depth constrained cluster

Dear R-Help Does "The R Package for Multivariate and Spatial Analysis Version 4.0 (Casgrain and Legendre, 2001)" exist on CRAN and under what name? It supposedly has a chronological clustering program ,CHRONO, that I would like to use. Alternatively, I would ask if there is a R based program that performs chronological clustering? Thanks Alex Alex Hanke Department of Fisheries and

Pearson correlation coefficient matrix with permutation test
Hello, I found an interesting program on Pierre Legendre's webpage: http://www.bio.umontreal.ca/casgrain/en/labo/corr_permute.html With this program one can compute a "Pearson correlation coefficient matrix with permutation test". This is exactly what I need as an R-package because so far I have only analyzed my data with the function cor(). However, I need additional

R-project [.com?] [.net?]
I got a shock a few days ago when I accidentally visited www.r-project.com . I thought that the r-project site had been hacked until I realised my mistake. There is also a site www.r-project.net. Both of these sites appear to be Japanese. Does anyone know anything about them? I suppose that it is not unusual for names close to those of popular sites to be used. It is good that they use a

indicator value in labdsv
Hi, I'm trying to find out what threshold of indicator value in labadsv should be used to accept a specie as an indicator one? So far I assumed that indval=0.5 is high enough to avoid any mistakes but it was based only in my intuition. I'd be greatful for any advise best regards Agnieszka

cran@ci.tuwien.ac.at is not responding?
Hi, I have submitted a package to CRAN in ftp://ftp.tuwien.ac.at/incoming/pastecs_1.0.tar.gz. The R extension manual advises to send a mail to cran at ci.tuwien.ac.at about it, but it fails. I have also tried WWWadmin at ci.tuwien.ac.at. Are these email adresses still valid? Best, Philippe Grosjean ...........]<(({?<...............<?}))><............................... ) ) ) )

vegan -varpart is bigger than 100% in total?
I am trying to find the percentage of the parameters explaining the bacterial community composition. I have one data matrix with relative abundance of OTUs and one with environmental parameters. I used varpart in vegan package but the values in the venn diagram is bigger than 100% in total.How is it possible? What might be the reason? Thank you library(vegan) gotud <-

plotting dendrograms from cluster analyses
Hi all, I have a bit of a newbie question here that I hope y'all can help with. I've run a cluster analysis using hclust on about 500 objects (using R1.3 under Win 2000). The problem is that the tips of the dendrogram are so close together on the plot that the labels overlap and are unreadable. I've used "cex" to reduce the label sizes but this isn't sufficient with so

list of functions flagged with debug() or trace()
Hello all, Since I got no answer to my first mail, I suspect I did not formulate my question adequately, so I try again. In R, one can debug or trace a function 'foo' with debug(foo) or trace(foo), respectively. This leads to a special treatment of the function 'foo' until one enter undebug(foo) or untrace(foo). I would like to know if there is a convenient way to know at any

"Transparent" background in graphics exported as metafiles
Hi, Under Windows, I am exporting graphs from R (in metafile -emf- format), and want to combine them using a graphic package. It happens that the background of the graph is represented by a filled rectangle (with the color given by bg=...). This is to be expected. However, I find no options to disable this and produce a graph with transparent background. Does such an option exist? If not, then

Supply linear constrain to optimizer
Dear R and S users, I've been working on fitting finite mixture of negative exponential distributions using maximum likelihood based on the example given in MASS. So far I had much success in fitting two components. The problem started when I tried to extend the procedure to fit three components. More specifically, likelihood = sum( ln(c1*exp(-x/lambda1)/lambda1 + c2*exp(-x/lambda2)/lambda2

Restricted Least Squares
Hi, I need help regarding estimating a linear model where restrictions are imposed on the coefficients. An example is as follows: Y_{t+2}=a1Y_{t+1} + a2 Y_t + b x_t + e_t restriction a1+ a2 =1 Is there a function or a package that can estimate the coefficient of a model like this? I want to estimate the coefficients rather than test them. Thank you for your help Ahmad Abu Hammour --------------

a problem with rep() ?
Colleagues ---------------------------------- System info: Version 1.2.3 (2001-04-26) on NT ESS v. 5.1.18 using emacs ver. 20.4 ---------------------------------- I am wondering if there is a problem with the function rep(). Both the commands using rep() below were expected to produce 8 twos, but only the second did. x <- rep(2,40*(1-0.8)) length(x) y <- rep(2,40*0.2) length(y)
