Dear R members, I am new in using frailty models in survival analyses and am getting some contrasting results when I compare the Wald and likelihood ratio tests provided by the r output. I am testing the survivorship of different sunflower interspecific crosses using cytoplasm (Cyt), Pollen and the interaction Cyt*Pollen as fixed effects, and sub-block as a random effect. I stratified

Hallo Friedrich, I have read your announcement, downloaded and installed it in R-0.61.3. But now I have problems :) > hc <- hierclust(dist(t(pollen)), method=3) Error in pmatch(x, table) : argument is not of mode character > hc <- hclust(dist(t(pollen))) > members(hc) Error in .Fortran("assgn", n = as.integer(n), nplus1 = as.integer(nplus1), : C/Fortran function not in

Dear Colleagues, I have x, y data (pollen and seed dispersal from oaks !) that I would like to fit with a function which look like this: p(a,b,x,y)=b/(2*pi*a?gamma(2/b))*exp(-(square_root(x?+y?)/a)power(b)) I am looking for a and b values that fit my data at best. Can someone give me hints to perform such an analysis with R ? Thanks a lot Sophie Sophie Gerber

Hi, I have a 4 column file (long/lat/elev/variable) and I tried to fit the values of my variable to the XYZ space using Tps and I keep getting the following message: Warning messages: 1: GCV search gives a minumum at the endpoints of the grid search in: Krig.find.gcvmin(info, lambda.grid, gcv.grid$GCV, Krig.fgcv, 2: GCV search gives a minumum at the endpoints of the grid search in:

Ladies and Gentlemen, The first public (beta) release of the package stratigraph is now available on CRAN: http://cran.r-project.org/web/packages/stratigraph/index.html It includes tools for plotting pollen diagrams, an implementation of an evolutionary algorithm for drawing stratigraphic lines of correlation, and several other functions for the analysis and plotting of geological,

Basically I have a controller with this: @lang = params[''lang''] || ''en'' @errors = request.raw_post @feed_stats = Net::HTTP.post_form(URI.parse("http://www.google.com/tbproxy/spell?lang=" + @lang), @errors) render :text => @feed_stats However whenever I run this I get an error message: undefined method `post_form'' for Net::HTTP:Class

Just a word to say thanks for your help. Yes, in order to install R packages I needed ncurses-devel which was not installed.

I''m writing a web app in which I have several ''windows'' in which the user can perform given functionality. So for example I have one window which manages images on a server (drag an image into a folder and the file physically moved on the server via ajax ) These images can also be dragged into another window to create a slideshow. My problem

Hello, Since English is my second language, forgive me for any typing errors. I have been studying rsync for my academic project. I learned quite a lot but I need little help. My question is, does rsync sends all checksum of a file at once or in batches. For example suppose I have a 2 GB file, so after generating checksum on receiver side, does the receiver sends all the generated checksum to the

Hi, I had R working since version 1.4. Then I bought a new HD and installed a RH 7.3 on it and since then I can no longer install any R package. Here is the failure message I obtain: ... g77 -fPIC -O2 -m486 -fno-strength-reduce -g -c sortm.f -o sortm.o gcc -shared -o fields.so css.o csstr.o cvrcss.o cvrf.o dchold.o dcopy.o ddot.o dlv.o

Dear R users, I am looking for some advice on the proper construction of a mixed model in R, using the difference in means as the response and treating within-means residuals as a random effect. I have a dataframe (my own, a snippet of which is given below) that is composed of observations of pollen viability in flowers along tree branches. Flowers (1 to 3 per position) were collected from

Hi, The animation package 2.0-0 is on CRAN now. This version is a milestone of the animation package. It includes a new function saveHTML() which uses a much more elegant interface and is consistent in syntax with other save*() functions such as saveMovie(), saveSWF() and saveLatex(). Lots of demos have been added to demonstrate the flexibility of this package, e.g. now we can get the snapshots

Hi! My plea to readers: =================== Pls., people who only want strictly technical issues to read, and frown at any broader context regardless how intrinsically related, but not strictly technically related, it might be, skip all the way, all the way to, search for exact words: "strictly technical" or visually, find two lines of sole "===" characters. Thank you!

Hi, The department of economics at our university (Budapest) is planning a course on numerical methods in economics. They are trying to decide which software to use for that, and I would like to advocate R. The other alternative is Matlab. I have found comparisons in terms of computational time for matrix algebra, but I don't think that is relevant: the bottleneck for economists is usually
