Hi! I'm puzzled by the return value of ifelse consider x<-integer(0) ifelse(is(x, "character"), paste(x), x) [1] NA whereas if (is(x, "character")) return(paste(x)) else x [1] integer(0) or x<-integer(1) ifelse(is(x, "character"), paste(x), x) [1] 0 work as I had anticipated. Is this correct behaviour? Regards, Matthias >sessionInfo() R

Hi, after updating R 2.5.0 devel yesterday we today observed many new unexpected failures in our daily package build and test system runs, which can be traced to recent changes in the implementation in try() (as noted in NEWS). Investigating this new implementation I come across an issue in conjuntion with using S4 classes and methods. try(expr) does not return an object with attribute

Hi, I just stumbled on the following apparent oddity: the package "datasets" does not appear to export anything out of its namespace: > ns_datasets <- getNamespace('datasets') > getNamespaceExports(ns_datasets) character(0) Not the case with other packages (example here with "utils"): > ns_utils <- getNamespace('utils') >

Hi, trying to install a package containing C code and requiring non-default configure argument settings the incantation (this has worked for R <= 2.8.1 on the same architectures) R CMD INSTALL --configure-args="--with-opt1 --with-opt2" packname does always result in a warning Warning: unknown option '--with-opt2' and consequently the option is ignored. Reverting the order

Hi, we noticed that since some time after Aug 24th the daily snapshots provided on ftp://ftp.stat.math.ethz.ch/Software/R/ no longer have their default tarball file name but dropped the date stamp, i.e. R-devel_.tar.bz2 Same for R-patched snapshots. Could one of the maintainers please take a look. We rely on the default naming convention for automatic builds. Regards, Matthias --

Hi, since a couple of days ago I see failures when using R CMD INSTALL -l lib path-to-src/pkg.tar.gz This occurs in automated library updating via a shell script and is caused by the immediate preceding call to leave an 00LOCK folder even though the package installation of that call succeeded. This occurs at random (no obvious/systematic correlation to package name or or such) and only for

Hi! Is it possible to avoid this error condition by specifying a command line option? I haven't found an obvious one in the manual. Background: We are using rsync for a live backup of our home directories. Emails are stored in Maildir format within the homedirectories. The rsync process is running for some time and in the meantime emails get deleted because users still have IMAP access. The

Hi, I encounter a problem with method dispatch with S4 classes, using the 'sealed' parameter in setClass. See that example below: setClass("X",representation(x="numeric"),sealed=TRUE) setGeneric("foo",function(x) standardGeneric("foo")) setMethod("foo",signature("X"),function(x) print("foo(X)")) x <-

Hi! I am currently testing a setup with dovecot's lda, the cmusieve plugin, pysieved and the avelsieve plugin for squirrelmail. The issue I am stumbling upon is that avelsieve is generating folder names including the namespace prefix when creating "fileinto" rules. E.g.: A rule: If the header "Precedence" contains "bulk", then file it into the folder

Hi! We are running dovecot-imapd on Debian sarge out of the backports.org packages (version 1.0.rc15-1~bpo1). We have ~ 80 clients using secure IMAP. I understand that imap-login has to run for every SSL connection. Thus I already increased the max value for the number of imap-login processes. But unfortunately dovecot is unresponsive from time to time. Where can I tune the installation? Do I

Hello R developers, installing R 2.0.0 from source on a Linux Debian system (gcc 3.2.2) - which worked just fine - I encountered the following problem when trying to update/install packages with the option --with-package-versions: example: RUnit 0.4.0 (also on CRAN) R20 CMD INSTALL -l /mnt/local/R/R-2.0.x-libs-EpiR --with-package-versions RUnit_0.4.0.tar.gz or after untaring R20 CMD INSTALL

Hi all, I'm a little surprised at > NULL == c("a", "b") logical(0) > all(NULL == c("a", "b")) [1] TRUE Reading the documentation for all() this was not clear for me to be expected. Originally the question came up when using > match.arg(NULL, c("a", "b")) [1] "a" where I had thought an error would occur. So

Hi, I wonder whether a package with namespace & dynamic library can be installed with the version number attached, ie. with the argument --with-package-versions. Is this currently possible? Using R 1.9.1 on Debian 3.0 I encounter a problem when trying to load a package installed with R91 CMD INSTALL --with-package-versions -l /mnt/local/R/R-1.9.x-libs-EpiR RIO in R started with R91

Hi, in the process of upgrading to R 1.6.0 I tried to install the latest RMySQL (0.5-0) package (Omegahat).

Dear list, yet another question on S4 method behaviour or rather its side effects: Consider the following example (see below) where a new S4 method 'predict' is defined which by doing so makes 'predict' a S4 standardGeneric. It works and simple test examples run but I'm cautious whether this is a 'silly' thing to do. Is this a dangerous thing to do, already known to

Hi, further down from the problem I asked about yesterday I encounter the following problem (please appologize for the lengthy mail - I have not found a brief example making the issue clear): - using R packages making use of namespaces & - S4 classes when using --with-package-versions in the install call: Pkgs install ok and the first pkg 'base' can be loaded in R

Dear list, this is not a problem report -- I would like to ask for advise what the recommended and safe way to perform the following is or what problems might arise in doing it differently. The question is: What is the recommended way of providing a default value in a prototype statement for a derived class for a slot provided from a parent class? I have first consulted the methods package

Dear all, I'm experiencing an unusual installation error for one package. Could anyone suggest how I can best investigate this from here please? I'm sorry this isn't very much to go on. Hopefully someone can point me in the right direction. The problem seems to be my library. It is large (3,418 packages) and I'd like to avoid rebuilding it, if possible. All packages are up to
