Johannes Huesing sent a message to stat-lisp-news at stat.umn.edu regarding an article in Linux-Magazin (German) on statistical software for Linux. I enclose excerpts. Can anyone summarize what was said about R in the article? If there is a web site for the article I would appreciate learning of the URL. I must...

Hi, I was wondering if anybody might have a reference for me: My R code is growing and getting more and more confusing. Thus, I figure it's time to switch to object-oriented again. I have done oo programming in C++ and Java before but the first few tutorial on R oo were a bit confusing for me. Is there any brief tutorial on oo programming in R especially for people who have done oo in Java

I'm interested in using R's plotting capabilities to try to generate a graph showing the relationship/pairing frequency of words appearing in a block of unstructured text. I don't have a specific algorithm or approach in mind, just looking to portray text in an interesting fashion. The output I'm hoping for is something like the following called a "Phrase Network":

I'm guessing there's a more efficient way to do the following using the index features of R. Appreciate any thoughts.... for (i in 1:nrow(dbs1)){ if(dbs1$Payor[i] %in% Payor.Group.Medicaid) dbs1$Payor.Group[i] = "Medicaid" if(dbs1$Payor[i] %in% Payor.Group.Medicare) dbs1$Payor.Group[i] = "Medicare" if(dbs1$Payor[i] %in% Payor.Group.Commercial)

Dear all, I have a list of time series and want to plot them. Is there a way that the dot-dot-dot argument of a function accepts a list as single arguments, such as funcall in several Lisp dialects? Greetings Johannes

Is anyone in the leadership of the R-project going to contact the New York Times and clarify that the article gave remarkably short shrift to the people who designed the user interface for R, to a large extent AT&T researchers from an earlier generation? It would be the appropriate thing to do. The R team did not develop the user interface for R, the designers of the S programming language

Dear expeRts, I am currently struggling with the problem of finding cut points for a set of stimulus variables. I would like to obtain cut points iteratively for each variable by re-applying a dichotomised variable in the model and then recalculate it. I planned to have fixed names for the dichotomised variables so I could use the same syntax for every recalculation of the whole model. I

The other day I was looking into one of the classics in resampling, Eugene Edgington's "Randomization Tests". This type of test is simple to do in R with things like a simple correlation, the sample () function is perfect for the purpose. However, things are more complex if you have grouped data, like a one-way ANOVA. The reason is that you have to avoid the consideration of

Dear List, I have a list of length ~1000 filled with numerics. I need to replace the elements of this list that are above a certain numerical threshold with the value of the threshold. e.g example=list(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1) threshold=5 <magic code goes here> example=(1, 2, 3, 4, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 5, 4, 3, 2, 1). I have written a crude

There have been several constructive responses to John Sorkin's comment, but none of them are fully satisfactory. Of course, if you know the name of the function you are looking for, there are lots of ways to search — provided that everyone calls the function by a name that matches your search. If you think there might be a function, but you don't know the name, then you have

Dear ExpRts, I would like to perform a function with two arguments over the rows of two matrices. There are a couple of *applys (including mApply in Hmisc) but I haven't found out how to do it straightforward. Applying to row indices works, but looks like a poor hack to me: sens <- function(test, gold) { if (any(gold==1)) { sum(test[which(gold==1)]/sum(which(gold==1))) } else NA }
