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

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. In the file>Display file GUI menu, if you try to display a file that is in use by

R1.6.2 winnt. file.choose() gives an error if the dialog is cancelled without choosing a file. This can be easily dealt with via try(), but I would have thought that a NULL or NA return would be the expected behavior. Cheers, Bert Gunter Biometrics Research RY 84-16 Merck & Company P.O.

Hi, all! My project today is to write a speedy colSums(), which is a function available in S-Plus to add the columns of a matrix. Here are 4 ways to do it, with the time it took (elapsed, best of 3 trials) in both R and S-Plus: m <- matrix(1, 400, 40000) x1 <- apply(m, 2, sum) ## R=16.55 S=52.39 x2 <- as.vector(rep(1,nrow(m)) %*% m) ## R= 2.39 S= 8.52 x3 <-

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 --

I've uploaded a package colSums_1.0.tar.gz to CRAN /src/contrib/Devel. It contains functions colSums, colMeans, colVars, colStdevs, rowSums, rowMeans, rowVars, and rowStdevs. These do simple, fast arithmetic on columns/rows of a matrix, or more generally across dimensions of an array, e.g. colSums(m) = apply(m, 2, sum) but faster. They should be compatible with the corresponding S-Plus

Full_Name: Doug Grove Version: 1.7.0 OS: Linux Submission from: (NULL) (209.31.211.56) Hi, Minor mistake in the documentation on the colSums page. In the ARGUMENTS section it states for 'dims' that: For `col*', the sum or mean is over dimensions `dims+1, ...'; for `row*' it is over dimensions `1:dims'. These two are reversed. Thanks, Doug Grove

Hi, all, I've been converting code from S-Plus ("S" for short) to R for a few weeks. Here are some differences I've found, aside from the big well-known ones (scoping, models, data storage) and the contents of Kurt Hornik's FAQ section 3.3.3. Let me start with the ones that seem like serious bugs or deficiencies: 1) LETTERS[c(NA,2)] in S is

Dear R-devel, I grabbed 1.7.0 beta from today. "make check" still fails at base-Ex.R. The last few lines of the output are: > lsf.str()#- how do the functions look like which I am using? Error in exists(nam <- nms[i], envir = envir, mode = mode) : F used instead of FALSE Execution halted Looks like the same problem as before, but at a different place. Mandrake Linux

Under v1.6.2, Windows NT4 OS, when a function contains an execution error and I have placed browser() in inside the function body, the call to browser is ignored. A brief example to illustrate: > foo <- function(x) { + y <- x ^ 2 + browser() + foo2(x) ## Intentional error + x ^ 3 + } > > foo(30) Called from: foo(30) Browse[1]> Error in foo(30) : couldn't find

Dear R-devel, I've run into this problem that when I hit c-c to interrupt a command or computation, the R session just ends. The info: R-1.4.1 compiled from source on Linux Mandrake 7.1. Dual P-3 Xeon with 2GB ram. 1. Compiled R with link to Intel Math Kernel Library (for fast BLAS), which needed pthread. C-c at the R prompt ends the R session. 2. Compiled R with link to (threaded)

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:

This is interesting: The crash does not happen if I run Rgui in MDI mode. The crash seemed to only occur in SDI. Andy =========================================================== For the record: Under Rgui, using the menu "File / Channge dir..." to change to a network drive crashes rgui. The crash happens if I browse to a folder on a mapped drive. I.e., if I type in

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 all, I'm running into a rather strange problem that hasn't happened before R-1.4.0. If I make a plot on a window() device, and use the menu to either save to a metafile or copy to clipboard as a metafile, I get an error message in the R console: Error: A metafile can store only one figure. This only happens when the lattice (and grid) package is attached, regardless of whether the
