Good morning, we recently observed a problem with importing S3 generics from a foreign package (without namespace), defining a S3 method in a package _with_ namespace and the `cleanEx()' function which is automatically generated and executed before examples are run by R CMD check. To be more precise. Package `strucchange' defines a S3 generic sctest <- function(x, ...)

Hi, is anybody out there who knows APL and would help me to translate 52 lines of APL code into propper R? best, Torsten

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 <-

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,

Hi, when we add \examples{ a <- 1:4 a %*% a } into a Rd-file are run R CMD check, the resulting R code is a <- 1:4 a So, %*% ... is lost on the way if I'm not totally confused.

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

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

Hmm, the problem I see here is that these implied classes are all inherently one-off. We also have > inherits(matrix(1,1,1),"numeric") [1] FALSE > is.numeric(matrix(1,1,1)) [1] TRUE > inherits(1L,"numeric") [1] FALSE > is.numeric(1L) [1] TRUE and if we start fixing one, we might need to fix all. For method dispatch, we do have inheritance, e.g. >

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

Hello, why does > test <- rank(sample(10)) > test [1] 4 8 9 10 2 1 7 6 3 5 > is.integer(test) [1] FALSE > is.double(test) [1] TRUE make sense in R-1.1.1?

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

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'. The same is true for R> cov(rnorm(100), rnorm(100)) Error in cov(rnorm(100), rnorm(100)) : 3 arguments passed to "cov" which requires 4. Best, Torsten R> version

New package `multcomp' for general multiple comparisons written by Frank Bretz, Torsten Hothorn and Peter Westfall We've uploaded the package `multcomp' to CRAN. The R package allows for multiple comparisons of k groups in general linear models. We use the unifying representations of multiple contrast tests, which include all common multiple comparison procedures, such as the

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
