Test for stationarity (pp-test). In R source code all other command executions I understood, but how I am getting the ssqrtl value ssqrtl <- .C ("R_pp_sum", as.vector(u,mode="double"), as.integer(n), as.integer(l), trm=as.double(ssqru), PACKAGE="ts") please explain the above command.

Hi ! I'm totally strange to R. And started downloading/reading dox because my gf. is using it in her university project. Now the problem sounds like this: I need to make a module/lib that will allow to call easaly R code/functions from C++ (C++ Builder 6). Is it possible without using any intermediate things like R-DCOM ? Please help ! P.S. Sorry ... no time for RTFM. Any idea/hint is

Hi, According to daisy function from cluster documentation, it can compute dissimilarity when NA (missing) value(s) is present. http://stat.ethz.ch/R-manual/R-devel/library/cluster/html/daisy.html But why when I tried this code library(cluster) x <- c(1.115,NA,NA,0.971,NA) y <- c(NA,1.006,NA,NA,0.645) df <- as.data.frame(rbind(x,y)) daisy(df,metric="gower") It gave this

Hi, I have been having some trouble using aov to do an anova, probably because I'm not understanding how to use this function correctly. For some reason it always tells me that "Estimated effects may be unbalanced", though I'm not sure what this means. Is the formula I am using written incorrectly? Below is the code I am using along with the data: > my.data response

Hi, I am writing a generic function and need to check if an arg is a data frame or not. I could use is.null(dim(x)) to get what i want. But i want to know if there is a function which can tell me whether it is a list, a numeric vector, a data frame, a factor and so on. Can R do that? thanks. -- Weiwei Shi, Ph.D Research Scientist GeneGO, Inc. "Did you always know?" "No, I did

Hi, text()'s pos does handle more dimensional labels, while adj does not - or how can I pass an array to text() and use the adj argument (skyblue text)? plot(-1:1,-1:1) text(c(0,0),c(0,0),c("a","b"),pos=c(1,2),col="red") text(c(0,0),c(0,0),c("a","b"),adj=cbind(c(1,2),c(1,1)),col="skyblue") Thomas

Hello All! I'm a new R user, with no much experience. I have a R script (downloaded from internet) which has user interaction using "readline()" function. So as I have to run it repeatdly (with some different options) I was planning to do it on a BATCH mode. Is there any way to answer the "readline()" questions from a batch file? How do I do that?

I have not included the previous postings because they came out very strangely on my mail reader. However, the question concerned the choice of minimizer for the zeroinfl() function, which apparently allows any of the current 6 methods of optim() for this purpose. The original poster wanted to use Newton-Raphson. Newton-Raphson (or just Newton for simplicity) is commonly thought to be the

Hello I know that R's string functions are not as extensive as those of Unix but I need to do some text handling totally within an R environment because the target is a Windows system which will not have the corresponding shell utilities, sed, awk etc. Can anyone explain the following gsub phenomenon to me: >
