Hello :-) We have Xapian and Omega working nicely. Now we would like more functionality at the browser UI, such as being able to specify date ranges and being able to search the file name including looking only for, say, .odt files. Question is whether the best choice for this would be to develop a template using OmegaScript or to switch to C++ or some other language. Availability of skills

Hi R-Experts, Currently I'm using an univariate time series in which I'm going to apply KalmanLike(),KalmanForecast (),KalmanSmooth(), KalmanRun(). For I use it before makeARIMA () but I don't understand and i don't know to include the seasonal coefficients. Can anyone help me citing a suitable example? Thanks in advance. ------------------------------------------

Dear Lists, I got the chance to review Bob Muenchen's book - R for SAS and SPSS users. While my detailed review is online at www.decisionstats.com, the book is a welcome addition in R Textbooks for beginners and an especially nice one for people who have experience in SAS and /or SPSS languages. AT 50 USD, it's reasonably priced for all geographies (;) , and quite handy as a refernce book

Dear R users, I am working on the Value at Risk (VaR) for the Operational risk. For a given loss data, we try to fit some statistical distributions using Kolmogorov-Smirnov (KS) test and A-D test and then for fitted distribution using the estimated parameters, the losses are simulated and the VaR is arrived at. The typical problem faced by the banks is the paucity of Internal loss data and thus

I am attempting to fit a partial credit model using the PCM() function in eRm. My data set comprises 88 items in 43 individuals with possible scores 0,1,2,3. Attempting either a PCM or RSM model fit simply hangs - no error messages but no return to command prompt and a continuously spinning "work in progress" indicator. The scores are from an instrument whose relevant psychometrics

Hello. I have come across a curious result that I cannot explain. Hopefully, someone can explain this. I am doing a 1-way ANOVA with 6 groups (example: summary(aov(y~A)) with A having 6 levels). I get an F of 0.899 with 5 and 15 df (p=0.51). I then do the same analysis but using data only corresponding to groups 5 and 6. This is, of course, equivalent to a t-test. I now get an F of 142.3

For reasons which I'll spare you, I'm writing a program to analyse R source code. This has led me to probe some of the darker corners of R syntax to find out what is supposed to happen. Now, from reading the R documentation (and the New S book &c) I know perfectly well that f(a, b, etc) <- x is supposed to turn into a <- "f<-"(a, b, etc, value=x) Except,

I would like to get some idea of which R-packages are popular, and what R is used for in general. Are there any statistics available on which R packages are downloaded often, or is there something like a package-survey? Something similar to http://popcon.debian.org/ maybe?
