Dear r-devel members, My Rcmdr package "depends" on several other packages (tcltk, grDevices, utils, and car) and "suggests" a number of others (abind, aplpack, colorspace, effects, foreign, grid, Hmisc, lattice, leaps, lmtest, MASS, mgcv, multcomp, nlme, nnet, relimp, rgl, and RODBC). The reason for the distinction is that I don't want all of these packages to load when

Dear r-help list members, Is there a way to test whether an object is an S4 object? The best that I've been able to come up with is isS4object <- function(object) !(is.null(slotNames(object))) which assumes that an S4 object has at least one slot. I think this is safe, but perhaps I'm missing something. Thanks, John -------------------------------- John Fox Department of

Dear list members, I think that it's a pity that there's no Windows binary for the rgl package on CRAN. I understand that rgl doesn't compile with the standard Windows tools and that there's a Windows binary on Daniel Adler's web site. But the lack of an rgl binary on CRAN provides presents a potential obstacle to at least some Windows users, such as many students in

Dear R-devel list members, I'm considering adding support for other languages than English to the Rcmdr package. I understand that the use of Tcl/Tk by the Rcmdr package means I won't be able to make full use of the internationalization facilities in R 2.1.0. I'm interested, therefore, in whether the following, more limited, strategy (which bears some similarity to the

Hello, I'm a admin over at Harvard University and I have quite a few users that use R predominately over VNC. In the past this has not been an issue, but after upgrading to R 2.0.0 they can no longer use RCmdr over VNC. When trying to use the package, they see the following: > library("Rcmdr") Loading required package: tcltk Loading required package: zoo Loading required

Dear R Development People: I have written a couple of plugins for Rcmdr and they do not seem to work with R-2.11.0.

Greetings, R-help! On 2 Fedora Core 2 Linux systems, i've completely erased the previous R and all packages and then installed R-2.0 and installed fresh packages. In using Rcmdr, I see some trouble and I wonder if other people see this and if it is due to the tcl/tk, or R, or Rcmdr. (If readers have not yet tried Rcmdr, I recommend it not just because of the GUI it provides, but also

Hi again, I run R under SuSE 9.2 Professional (installed via rpm) and I am trying to install some packages from CRAN. The trouble is, after successful installations, my destdir directory is deleted...! My command: install.packages("Rcmdr", "/usr/lib/R/library", CRAN="http://cran.r-project.org", destdir="/home/adi/Kituri/R.packages", dependencies=TRUE)

Dear r-devel list members, I've prepared a version of the Rcmdr package that uses the new tools for internationalization and localization in R 2.1.x. For the present, this is the development version of the Rcmdr package (1.1-0), available at <http://socserv.socsci.mcmaster.ca/jfox/Misc/Rcmdr/index.html>. There is currently a French translation provided with the package, courtesy of

I'd like to announce a new version, 1.3-0, of the Rcmdr package. The Rcmdr package provides a basic-statistics graphical user interface (GUI) to R. Beyond small changes and additions, this new version of the package makes provision for "plug-ins" that permit extension of the Rcmdr GUI without altering and rebuilding the Rcmdr source package or modifying the installed package. An R

Dear list members, I've just uploaded version 1.0-0 of the Rcmdr package to CRAN.

Dear DevelopeRs, I've been struggling with the new regulations regarding modifications to the search path, regarding my Rcmdr plugin package RcmdrPlugin.DoE. John Fox made Rcmdr comply with the new policy by removing the environment RcmdrEnv from the search path. For the time being, he developed an option that allows users to put the environment from Rcmdr (RcmdrEnv) on the search path,

Dear Andy and Peter, My apologies for chiming in so late, but I was out of town and just caught up with R-help today (and an impressive amount of material accumulates on R-help in a couple of weeks!). Although I develop the Rcmdr package on a Windows system, I test it under Linux as well -- most recently on Ubuntu 7.04 with R 2.5.0. Curiously, the windows for Rcmdr 1.3-5 look normal to me, as I
