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 the analysis by developmental stage (G_stageSM) as an ordered factor (two classes). There is a lot of tied deaths in this dataset. Below is the analysis summary. coxph(formula = Surv(Death_day,...

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 load table Since I have a snapshot from May 22 I put i...

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...

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, biological, ecological, and paleontological data distributed through time or stratigraphic depth. There are still so...

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.

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

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 apical and basal positions along the same branch, and I'm predicting that the within-branch difference between the mean viabilities at each position is a function of the distance separating the position...

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
