Not sure whether this is a feature or bug -- but it does not appear to be documented. R1.6.1 on Windows NT 4.00.1381 Objects assigned in the Rprofile.site file (e.g. foo<-'something') are put into package:base not .GlobalEnv on startup. Objects assigned in the .Rprofile file are put into .GlobalEnv. This doesn't seem consistent to me. The objects exist in base only for the

Folks: Winnt; R1.7.0 (freshly installed) running under Rgui.exe.,MDI=yes. The following is repeatable: On startup, in my Rprofile.site file, I use winMenuAdd() etc. to install some user menus. However, they do not appear when R GUI window opens. If I minimize and restore the window, the added menus now are present. The exact same procedure under 1.6.2 with exactly the same Rprofile.site and

All: The select.list() command brings up a "modal dialog box with a (scrollable) list of items ..." etc. -- i.e., a GUI control. I also know about winDialog, file.choose and the winMenu commands. What other such GUIisms are built into ** base ** R (I know about the tcltk package)? Or, better yet, how can I search on or list them? Many thanks. Bert Gunter Biometrics Research RY 84-16

R-Listers: A very minor -- and maybe silly -- question just for personal enlightenment. In S (either R or S-Plus, AFAIK) when one types or pastes a trellis graphics command into the commands/console window, the graph is automatically produced: e.g., trellis.device(...) xyplot(y~x) If one puts these in a function and calls the function, the same occurs. However, if one sources in these command

Hi Bert, Thanks for the suggestions. I tried lme with different control parameters, and also tried using "ML", instaed of "REML", but still got the same answers. Yes, I hope some gurus on this list could give me some hints. Thanks --- "Gunter, Bert" <bert_gunter at merck.com> wrote: > But they are close. This is almost certainly a > numeric issue --

My apologies if these are known -- I'm new to R (moved over from S-Plus). All on Windows NT GUI, R1.6.1 and associated packages. 1. save(x) gives the following error message: Error in save(x) : `file' must be non-empty string According to the save() help file, the empty string is the default. 2.

Dear R-help, Has anyone notice the problem that, on Windows (NT and XP), when printing a graph using the "File -> Print..." menu in the graphics window to print the graph, that line width seemed to be ignored in the printed output? For example, if I make a plot with plot(1:10, type="l", lwd=5), it looks right on screen, but when printed out using the menu, it looks like

Dear R-devel, I recall that there used to be a mechanism to get around the requirement that all objects in a package have associated documentation; i.e., a way to specify a list of objects (mostly functions) that are not considered as part of the package API. Is this still available? I cannot find any mention in R-exts. I realize that the way to go is to have a name space, and eventually

[I believe few users manipulate formulae and model frames like this, so I'm posting here instead of R-help.] I just found out that model.frame() includes all terms, including those preceded by "-" in the formula, in its output (as mentioned on its help page). Is there a recommended way of excluding "negative" terms? My guess is that I can use info in the terms attribute

Dear R-help, I've been compiling R from source on our Linux boxes for quite a while. One thing that bugs me is that I always get an error when make check-all where it choked up running tests/internet.R. That wasn't a big deal, as I can run install.packages()/update.packages() fine, and that's all I use the 'net connection for. The problem is that it takes a _long_ time to fail

With the same system configuration (WinNT4 SP6 and 1.7.0), I get such a Dr Watson crash each time I try to use the Change dir... command in the File menu of Rgui.exe. I doesn't seems to happen if I do this immediately after starting R but well if I already did some computation. I don't have any problem by using directly setwd().

Dear R-devel, I'm encountering a strange problem in a Rd file that I'm working on. In the "Value" section, I have something like: ===================== \value{ An object of class \code{randomForest}, which is a list with the following components: \item{call}{the original call to \code{randomForest}} ... For classification problem, the following are also included:

Dear R-devel, Kurt had alerted me to the problem that the randomForest package that I maintain has been failing checks in R-devel. However, I just can't see why or where it's failing. I'd very much appreciate any pointer. The failure occur when running the example code in varImpPlot.Rd: > varImpPlot(mtcars.rf) Error in par(opar) : invalid value specified for graphical parameter
