hi, i am not able to extract the p-values from the Manova function in the car library. I need to use this function in a high-throughput setting and somehow need the p-values produced. Any ideas?

Hello, I have a dataset with proportions that vary around a fixed mean, is it possible to use betareg to look at variance in the dispersion parameter while keeping the mean fixed? I am very new to R but have tried the following: svec<-c(qlogis(mean(data1$scaled)),0,0,0) f<-betareg(scaled~-1 | expt_label + grouped_hpi, data=data1, link.phi="log",

Hi , is it possible to calculate ld-measures D, D', r and perhaps corresponding p-values with r IF THE PHASE IS KNOWN? The genetics - package provides the LD function only for ambigious phase. Thank you very much Bettina Kulle

I am using 'tm' package for text mining and facing an issue with finding the frequently occuring terms. From the definition it appears that findFreqTerms and minDocFreq are equivalent commands and both tries to identify the documents with terms appearing more than a specified threshold. However, I am getting drastically different results with both. I have given the results from both the

Problem on flexmix when trying to apply signature developed in one model to a new sample. Dear R Users, R Core Team, I have a problem when trying to know the classification of the tested cases using two variables with the function of flexmix: After importing the database and creating a matrix: BM<-cbind(Data$var1,Data$var2) I see that the best model has 2 groups and use: ex2

Dear list: I would like to recreate how the artificial data set BregFix was generated in package flexmix (thanks Bettina and Friedrich). The data set is thoroughly described in Grun and Leisch's Computational Statistics & Data Analysis 51(11) :5247-5252 but references to the appropriate seed number(s) are missing (providing these details was certainly beyond the scope of the authors' work). To this end,...

Hello, I would like to annotate a graph with the expression 'alpha = 5%' (the alpha should be displayed as the greek letter). I tried > text(1,1,expression(alpha == 5%)) which gives a syntax error. escaping the percent sign (\%) or doubling (%%) does not help. What do I do? Thanks, Martin Keller-Ressel -- Martin Keller-Ressel Research Unit of Financial and Actuarial

Hallo! I want to use the package bayesmix. Trying the examples I had no success. The reason is, I think: > haveJAGS() [1] FALSE Have read of JAGS executable (I could not find JAGS.exe in my R directory). What is JAGS? Where can I find or download it? Karl

...readsheet? I have my microarray data now in a .csv or .txt file with phenotype in the first row, class in the second row and then gene expression data starting from the third row. first column are the affy-IDs. I have two classes. I would appreciate it, if someone could help me out with that!!! Bettina

Dear R-helpers & Friedrich Leisch, I'm trying to fit a mixture of regression models on attached data set by doing the following: agl <- read.table("agl.txt") mod1 <- flexmix(resp~gng+csc|Subject,data=agl, model=FLXglm(family="binomial"),k=2) The result is a (varying) number of the following warnings: Warning messages: 1: non-integer #successes in a

I am trying to cluster some binary data using k-means . As the regular "kmeans" available from stats package in R does'nt provide the option to change the distance method. I was wondering there is any package available to specify type of distance measure to be used in k means clustering in R. Especially distances like "Jaccard" which is good for binary data.

..."empirical" computes the entropy of the empirical probability distribution. This probably means it is using this definition of the entropy: H = sum_x sum_y p(x,y)* log( p(x,y)/ (p(x)*p(x)) ). Is this correct? 2.) Which is basis is used for the log? Thanks a lot for your in advance. Bettina Keller
