Hi, the following example aiming at a class containing a logical slot segfaults under R-1.9.0 when `gctorture(on = TRUE)' is used: Code code (dummy.c): #include <Rdefines.h> SEXP foo() { SEXP ans; PROTECT(ans = NEW_OBJECT(MAKE_CLASS("test"))); SET_SLOT(ans, install("lgl"), allocVector(LGLSXP, 1)); LOGICAL(GET_SLOT(ans,

I don't use SPSS but following through on your detective work can provide the likely answer. First note that both date numbers are evenly divisible by the number of seconds in a day, i.e. 24*60*60. This suggests that these numbers are seconds since some origin. Since we know "2003/02/11" corresponds to 13264300800 we deduce that the origin must be spss.orig <-

Dear helpers I want to use rpart several times in a loop to build a classification tree. My problem is that rpart needs a formula as argument and for that the variables need to have names and this doesn't happen in my case. Every iteration in the loop has a different dataset with several variables (ex. 38 or more) and so I can't type the names by hand every time. Is there any function

Summary: + I am writing an R extension that needs to call dmvnorm more than 10,000 times during a model fitting computation. + My extension uses openmp for parallel execution. + As of R 3.0, it is no longer permitted for threads to call the R interpreter because there is a stack overflow check that always trips because the thread's stack is different from what R is expecting. +

Dear developeRs, I thought that backslashes can be escaped in the usual way (and I think I did this before) but I can't see why R> gsub("\\", "x", "\alpha") Error in gsub(pattern, replacement, x, ignore.case, extended, fixed, useBytes) : invalid regular expression '\' gives an error. Or am I just blind? Best, Torsten R> version

I am using the .Call interface to call c++ code from R. For that, I am trying to create a dynamic library (mylib.so) using "R CMD SHLIB" by linking my own c++ code and an external c++ library (blitz++). The makefile works fine on my Mac, produces mylib.so and I am able to call .Call() from R, but on a linux server (I think Debian), I got the following error: ---------- /usr/bin/ld:

Hi, currently the "label" and "edgetext" attributes of a dendrogram are coerced to character before they are added to a plot with `text'. Is there a specific reason to do so (expect for the determination of the size of the character string to be plotted)? Otherwise one could plot the attributes directly via diff dendrogram.R /usr/src/R/src/library/stats/R/dendrogram.R

Hi, a friend of mine came across this R> x <- 1:5 R> cbind(x,x) x x [1,] 1 1 [2,] 2 2 [3,] 3 3 [4,] 4 4 [5,] 5 5 R> rbind(x,x) [,1] [,2] [,3] [,4] [,5] x 1 2 3 4 5 x 1 2 3 4 5 x is a vector and therefore has no dim-attribute. Obviously cbind treats x as a col-vector but rbind treats x as a row-vector, that is: two functions have a different

Hello, I use t.test for normal distributed and wilcox.test for non-normal distributed samples. It is easy to write a function for t.test that calculates the effect size, because all parts of the formula are available from the t.test result: r = sqrt(t*t / (t*t + df)) However, for Wilcoxon tests, the formula for effect sizes is: r = Z / sqrt(N) I wonder how I can calculate the Z-score in R for

Hi, in last nights alpha version, `var' is broken: R> var(rnorm(100)) Error in var(rnorm(100)) : 3 arguments passed to "cov" which requires 4. which I suspect is due to recent changes to `cov'.

Hi, did anybody manage to compile F90 sources in an R-package? The major problem is, at least in my opinion, that non of the "free" F90 -> F77 converters is working correctly, at least for the F90 sources I need to compile.

I suppose that multcomp in R and multicomp in S-Plus are related and it appears that it is possible to use multicomp with lme in S-Plus given the following correspondence on s-news sally.rodriguez at philips.com 12:57 p.m. 24/04/03 -0400 7 [S] LME summary and multicomp.default() Is it possible to use multicomp with lme in R and if so what is the syntax from a simple readily available

Dear R users, we are trying to build a R package that includes a precompiled shared library, let's say mylib.so. We created the skeleton of the package and we moved the mylib.so file into the libs folder that we created at the same level of the folders man and R. Moreover we created the file NAMESPACE and we added the line useDynLib(mylib, .registration=TRUE). The building step seems to work
