...onal survey-studies. The effect sizes would be correlations. The R packages "meta" and "rmeta" are, as far as I can see, set up for analysis with effect sizes for differences (i.e. comparison of the means/odds-ratios of experimental and control group). Only the function "metagen" from the "meta"-package looks like it would work with correlations. The problem here: One would need to know the standard error of the correlation. The SE is not usually reported in the studies I have (only means, SDs and Alphas for the single variables). So the SE would have to be...

Dear Sir or Madam, I am trying to plot forest plot. I extracted odds ratio and their corresponding 95% confidence interval from papers, then I calculated the log(OR) and standard error using the following command OR<-metagen(logOR,selogOR,sm="OR") forest(OR,comb.fixed=TRUE,comb.random=TRUE,digits=2) However, it does not produce a forest plot. Can someone kindly help? Thank you in advance. Best wishes weiwei [[alternative HTML version deleted]]

Does anyone know which package include the computation of Cochran’s Q statistic in R? jlfmssm [[alternative HTML version deleted]]

Full_Name: Klaus Hermann Version: 1.5.0 OS: SUNRAY - Unix Submission from: (NULL) (213.61.59.254) if we produce a numeric vector of length 0 and want compute the sum over its elements the sum function returns 0 - this is obviously misleading. Better would be to return NA and give a corresponding warning. There should be a unified strategy to handle vectors of length 0. For example the functions

Hey, hopefully there is an easy way to solve my problem. All that i think off is lengthy and clumsy. Given a data.frame d with columns VALUE, FAC1, FAC2, FAC3. Let FAC1 be something like experiment number, so that there are exactly the same number of rows for each level of FAC1 in the data.frame. Now i would like to scale all values according to the center of its experiment. So i can apply s

...Martin Lauss http://crantastic.org/packages/rocc Functions for a classification method based on receiver operating characteristics (ROC). Briefly, features are selected according to their ranked AUC value in the training set. The selected features are merged by the mean value to form a metagene. The samples are ranked by their metagene value and the metagene threshold that has the highest accuracy in splitting the training samples is determined. A new sample is classified by its metagene value relative to the threshold. In the first place, the package is aimed at two class prob...
