Hi all, I just stumbled across the difference between explicit and 'automatic' row names for data frames. Is there a quick way to find out if a data frame has automatic row names or not? Of course I know this for data frames that I create myself, but what if a function needs to extract this information for an argument? The following example shows that this property is not easily

Dear list members, I have defined a binary operator %append% with methods for some S4 classes. In my documentation file, I want to list the methods explicitly by using e.g.: \S4method{\%append\%}{RecLinkData,RecLinkData}(x, y) In the HTML documentation this comes out right as ## S4 method for signature 'RecLinkResult,RecLinkResult' x %append% y , but R CMD check

Hi all, I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave afterwards. Now, when Sweave comes to a figure chunk, it sees that there is an X server running and tries to show whatever I plot

Hello all, I posted the following bug last week: # These calls work correctly: match(c("A", "B", "C"), c("A","C"), incomparables=NA) # okay match(c("A", "B", "C"), "A") # okay match("A", c("A", "B"), incomparables=NA) # okay # This one causes R to hang: match(c("A",

Hi all, I stumbled across the following, in my opinion surprising, behaviour of read.table: > data <- read.table(stdin(), sep=",") 0: 1, 2, 3 # Some comment 1: > sapply(data, class) V1 V2 V3 "integer" "integer" "numeric" I was surprised to find that V3 has class "numeric" despite its apparent integer value. I

Dear R-devel members, I would like to compile a package with two seperate shared libraries. For example, in a package 'foo', a file 'bar.so' built from a distinct set of source files should be installed in addition to the default 'foo.so' (or .dll on windows). Does anyone know about a way to achieve this without having a custom Makefile, e.g. via 'Makevars'?

It's been a while since this thread appeared, but I had the same problem and don't want to keep the solution for myself. A small, reproducible example: <<cache=true>>= a=1 @ <<>>= a+1 @ Compiling with cacheSweave gives an error: > library(cacheSweave) Lade n?tiges Paket: filehash filehash: Simple key-value database (2.0-1 2008-12-19) Lade n?tiges Paket:

Hi all, I am posting this again because I got no reply on r-help. Maybe the devel-list is the right place for this kind of question. I've run into the following problem with Sweave: I frequently run Sweave from a xterm console within an X session owned by a different user, i.e. my colleague is logged in on this computer and I do "su" with my username and start R and Sweave

Hi all, I have a function which makes use of missing() to determine which arguments are provided in the call - basically, there are two sets of arguments that map to different strategies the function uses to fulfill its task. After conversion to an S4 generic I've run into the problem that if a method uses extra arguments that are not in the signature of the generic, usage of missing()

Dear useRs, This is to announce the RGtk2Extras R package is available on CRAN in version 0.5.1. This package provides useful extras for R programmers who wish to create graphic user interfaces. It is based on GTK, using Michael Lawrence's RGtk2 package and John Verzani's gWidgets, and some ideas from John Verzani's traitr package. The first major feature of RGtk2Extras, the

Hi all, I use txtProgressBar to monitor progress of large computations. What I miss is the ability to redirect the progress bar to a stream other than stdout, specifically to the message stream. This would be useful for running Sweave scripts: When redirected to stderr, the bar could be visible even though console output is diverted to the output file (and there would be no cluttering of the

Hi, Is it intentional that LazyValueInfo.getPredicateAt doesn't solve for the value and only takes assumptions into account? getPredicateAt gets lattice value from cache using getValueAt call: LVILatticeVal LazyValueInfoCache::getValueAt(Value *V, Instruction *CxtI) { ... LVILatticeVal Result; mergeAssumeBlockValueConstantRange(V, Result, CxtI); ... return Result; } Other

Dear Samba Member, i've decide to write to the samba lists in the hope of Your help.

Hi all, Installed rattle and the required GTK+, but ran into problems. did some research on the net which recomened removing GTK+ and insalling it from within R from the package RGTK2 which I did but that didn't resolve the problem. I get two different errors one is noticed as soon as I try to run rattle as bellow > rattle() ##after this command I get the following msg.

Dear R-users, I wanted to inform you that a new package called R2STATS is available, as a graphical front-end for the glm() and glmer() functions. The GUI is based on the RGTk2 and gWidgets packages by Michael Lawrence and John Verzani, and so requires that the GTK+ library be installed first on your system. This is done "automagically" when installing the RGtk2 package (or the

Hello, I am using Dovecot 1.2.9 on a 32bit on Ubuntu 10.04.2 LTS. We got one user who uses folders in an "exessive" way. He has got 704 subscribed folders. That means about nearly 3000 folders on the filesystem. Since ~ a week the user couldn't work because of timeouts when connecting to Dovecot (IMAP). Thunderbird doesn't show any folders - timeout - the webmail System

Dear R-devel: Would R core team consider endorsing a graphical toolkit and trying to facilitate development of little GUI tools? I need a gui matrix editor for users that want to be able to write matrices that are later used to simulate data. Instead of teaching them to write a covariance matrix (for example, for mvtnorm), I want to tell them run a function that pops up a table they can fill
