R-2.9.1, Windows7 Dear list, I have a question to you that seems very simple to me, but I just can't figure it out. I have a dataframe called "ratings" which contains the following variables: evalR1, evalR2, evalR3, evalR4, scoreR1, scoreR2, scoreR3, scoreR4, opinionR1, opinionR2, opinionR3, opinionR4. (there are more variables, but this gives an idea of the data structure). What

WinXP, R-2.9.1 LS., I have been trying to solve a (for me) tricky issue. No matter what I've tried, I just can't find a way to do this. This is the issue: I have a text file (ansi text) "titles.txt" with lines of text; here is an example of such a file: >>>>> a brief history of polio vaccines anti-vaccination movements and their interpretations early warning

Hi, I want to estimate a model of the following form: y = a1W1y + X1beta1 + e e = a2W2e + X2beta2 + nu with y a vector of proportions or counts and W a matrix of weights. In other words, autocorrelation occurs for the response variable y and for the disturbance term e. Ideally, at either level multiple W matrices could be included and X1 and X2 could be (partly) different (or X2 could be

Win7, R2.11.0 I am working on a report together with several co-authors. The data concern several performance measures on a set of groups. These measures are scored by external judges. We report findings on several datasets, including several of the 6 ICC's discussed by Shrout & Fleiss (1979). We determine these using the icc function from the irr package. We have also used the ICC
