I am investigating how well R/tcltk is supported on different system and I ran into the same problem as Christian Schulz reported on February 7, 2002. I am using [R] v1.4.1 on WinMe and ActiveTcl 8.3.2. Loading tcltk within Rgui works just fine and both demo(tkdensity) and demo(tkttest) works as expected. However, when I start R from my Cygwin terminal dyn.load() fails to load the library: % R

Where should the setClass() ('methods' package) calls be placed in a package? I try to follow a one-class-one-file principe, but since setClass("ClassA", "ClassB") has to come a after setClass("ClassB", [snip]) it is not possible to fully follow this rule. So the best I can do now is to put all setClass() calls in a file named "000.R" (I know this

Full_Name: Henrik Bengtsson Version: 1.3.1 OS: WinMe Submission from: (NULL) (130.235.2.229) I found the following bug on WinMe (I call it a bug, since the behavior is different on WinMe than for instance Sun Solaris): When calling file.exists() with an existing directory name ending with a "/" (slash) [R] on WinMe will return FALSE, but when doing the same without the ending

Dear all, I can't see how setGeneric() works. I know perfectly well how to define library(methods); setClass("Square", representation(side="numeric")); # Will become the default method. getArea <- function(object) { stop(paste("Method getArea() is not defined for this class:", data.class(object))); } setMethod("getArea",

I might be wrong, but didn't the following work before R v1.4.x? R --vanilla > df <- data.frame(-10:10) > abs(df) Error in abs(df) : non-numeric argument to function I have tried this on both Rv1.4.1 on WinMe and Rv1.4.0 on Solaris 8. I regexp searched bugs.r-project.org on "abs" but I found nothing about this. I can't see why abs(df) shouldn't work when sqrt(df),

Hi, I am trying to find the fastest way to "find the last index k such that x[k] < y in a *sorted* vector x" These are my two alternatives: x <- sort(rnorm(1e4)) y <- 0.2 # Alt 1 k <- max(1, sum(x < y)) # Alt 2 "divide and conquer" lastIndexLessThan <- function(x, y) { k0 <- 1; k1 <- length(x) while ((dk <- (k1 - k0)) >

When loading a package with library(APkg) or require(APkg) I would like to make sure that (1) the correct version of [R] is installed. If not an informative error message should be given. I would also like to make sure that (2) another required package which is loaded from within the APkg package (by require(OtherPkg)) is of a certain version or later. First of all, I believe that the check

Dear [R] people, I am looking for a method to test if there are any changes (jump points) in a time series data set or not. If there are, I would like to identify the jump points. All the data is available from the beginning so an offline method could be used. The current data set that I have could be seen as a time series with five almost equally sized segments that stands out to have different

I use smooth.spline(x, y) in package modreg and I would like to get value of penalized log likelihood and preferable also its two parts. To make clear what I am asking for (and make sure that I am asking for the right thing) I clarify my problem trying to use the same notation as in help(smooth.spline): I want to find the natural cubic spline f(x) such that L(f) = \sum_{k=1}{n} w[k](y[k] -

Is there a weighted median function out there similar to weighted.mean() but for medians? If not, I'll try implement or port it myself. The need for a weighted median came from the following optimization problem: x* = arg_x min (a|x| + sum_{k=1}^n |x - b_k|) where a : is a *positive* real scalar x : is a real scalar n : is an integer b_k: are negative and positive scalars

Dear R-core Team, As Thomas Lumley pointed out in one of his e-mails one can use commandArgs() to get a copy of the command line arguments supplied when R session was invoked and then use grep to extract parameters of interest. His solution works very well if the custom options are passed by names, e.g. --my-option=value, but what if one wants to pass parameters by their positions. Then it's

Full_Name: Henrik Bengtsson Version: R v1.4.0 OS: Solaris 8 Submission from: (NULL) (130.235.3.49) When I am trying the following on Rv1.4.0 on Solaris 8, I get that the "cannot close output sink connection": % R --vanilla tmpfile <- tempfile() # Create a filename that does not exist for(k in 1:100) { cat(k, ": "); try(fh <- file(tmpfile, "r"))

I am trying to build [R] v1.3.1 *locally* on a Sun Solaris 8 machine. One problem I am currently struggeling with is to make the command-line history function to work. I have installed GNU readline version 4.2 (latest version). Looking at the "config.log" file it seems that all readline related checks, e.g. "readline/history.h", passes (they did not before installing GNU

A binary distribution of R-1.4.0 to run on Windows 95, 98, NT4.0, 2000 and XP on Intel/clone chips is available at http://sirio.stat.unipd.it/RWin It will be mirrored at a CRAN site near you in a couple of days. See http://sirio.stat.unipd.it/RWin/CHANGES for a list of Windows-specific changes. guido masarotto

Hi, I am not sure if this is a bug or a non-implement feature of text-drawing functions with TeX-style expression, but hat() and some of its equals does not get the right "bounding boxes" if they are put in sub- or superscripts. For instance, for the expression 'b[hat(a)]' the hat() seems to shift 'hat(a)' too much to the right of 'b'. Try the below example and

Before reinventing the wheel, is there a package for working on (nice) sets and intervals, where one can for instance check if a set of intervals contains a scalar, taking the union and intersection of some intervals etc? Example: # Defining the set i = [1,2) + [3.5, 10] i <- c(1,2, 3.5, 10) attr(i, "include") <- c(TRUE, FALSE, TRUE, TRUE) x <- 0:12 # Get

Hi, just in the process of updating my packages for R v2.0.0 and I have not had time to followed the R v2.0.0 discussions so maybe my questions have already been answered. A concern I have is that when creating packages they should be backward compatible with R v1.9.x for a while until all users and computers has migrated to R v2.0.x. It is pretty straightforward to setup my packages so that

What about adding the argument 'flush=FALSE' to read.table() for the option to ignore trailing elements on each row? This feature already exists in scan(), which is called internally by read.table(): flush: logical: if `TRUE', `scan' will flush to the end of the line after reading the last of the fields requested. This allows putting comments after the last
