Hi, I am a little bit surprised by the following output of 'formals'. Is this the intended behavior? > f <- function(a=1,b=-1) { a+b } > class(formals(f)$a) [1] "numeric" > class(formals(f)$b) [1] "call" Josef -- ----------------------------------------------------------------------------- Josef...
Full_Name: Josef Leyold Version: 2.9.0 (2008-11-20 r46997) OS: Linux Submission from: (NULL) (137.208.56.12) Hi, the command dchisq(x=Inf,df=10,ncp=1) causes R to hang in an (almost?) infinite loop...
Hi, I wonder about the reason for the following lines: $ diff ~/local/lib64/R/bin/build /usr/lib64/R/bin/build 40c40 < my $revision = ' $Rev: 46832 $ '; --- > my $revision = ' $Rev: 45803 $ '; 576,579d570 < if(-r "Makevars") { < $makefiles .= " -f Makevars"; < R_system...
Hi, i have used S4 classes to implement a unified access to random number generators (package rstream on CRAN). I have used a construct to allow optional arguments: if(!isGeneric("rstream.sample")) setGeneric("rstream.sample", function(stream,...) standardGeneric("rstream.sample...

Dear maintainers of the parallel package, I ran into an issue with the parallel package in R-3.1.0. The following code prints the message "NULL!" quite a lot. library(parallel) for (n in 1:1000) { p <- mcparallel(sqrt...
Hi, I am writing a package that provides an interface to other uniform random number generators. It uses RNGkind(kind="user-supplied") and a function double *user_unif_rand() as described in the help page "Random.user". When looking into...
Dear Brian and Uwe, Thanks a lot for the clarification. I made the naive assumption that numeric constants in R are similar to those in C. Two questions still remain: (1) when I have a function f<- function(a=1...
Hi, Our department has detected a bug in the implementation of the Kinderman-Ramage generator for normal random variates in version 1.7.0, which can be seen from the below R session. (Consecutive calls for chisq.test(...) always gives...
Hi, As you probably know, there is a problem with the interface for adding uniform random number generators in R (see by article in R News 5/2, November 2005). There exists a mechanism called "user-supplied" that allows users...
Hi, I sometimes play around with extreme parameters for distributions and found that qbeta is not always monotone as the following example shows. I don't know whether this is serious enough to submit a bug report (as this example...
