similar to: Pasting into Tk table widget?

Has anyone written a matrix editor or data.entry() replacement using the Tk table widget? I've been playing around with the examples at http://bioinf.wehi.edu.au/~wettenhall/RTclTkExamples/tktable.html and making some progress, but I'd rather not spend much time on this if someone else has already done it.

In package A I have askForString(), which asks the user for a string. Also in package A I have defined ssh(), which calls askForString(). Package B has package A as a prerequisite. In package B I redefine askForString() to take advantage of a nicer user interface made available by B, namely the Emacs mini-buffer prompt. Packages B and A are both on the search path, with B ahead of A. If I call

Is is possible from within a function to cause its caller to return()? I have a function that lets user make edits to certain objects, and then checks that the edited objects still make sense. If they don't, the function puts up a notifier that the edits are being discarded and then returns, something like: if(badEdits){ notifyDialog("bad edits will be ignored")

I'm writing a package that interfaces to the FAME database, via a library of compiled C routines accessible through a Linux .so file. My .onLoad() function loads the .so like this: dyn.load("/opt/fame/timeiq/lib/linux_x86/libjchli.so", local = F) and after that I also load my own fame.so via library.dynam("fame", package = "fame") The code in fame.so uses

Dear all, please excuse the somewhat special question: >From within R I create a Tk windows with a list of checkboxes, which can bekome too long for the screen. The obvious solution would be to put all checkboxes into a frame and make that scrollable. Alas, there are (for whatever reason!) no scrollable frames in Tk :-( The usual workaround is to put widgets (my checkboxes) into a textbox,

One hassle I could do without is the necessity of writing C wrapper functions like this: void fameInit(int *status){ cfmini(status); return; } when I want to call a library function (cfmini, in this case) that takes an int argument. The .C interface only lets me pass a pointer to an int, rather than the int itself. Is there any chanch that .C could be enhanced to allow passing arguments by

I have an S3 class called "tis" (Time Indexed Series) which may or may not have multiple columns. I have a function "[<-.tis" that I've reproduced below. My question is this: inside of "[<-.tis", how can I distinguish between calls of the form x[i] <- someValue and x[i,] <- someValue ? In either case, nargs() is 3, and looking at the values

1. I want to change the mouse cursor over my window into a wait/watch icon while R computes. Can this be done directly? Some ancient tcltk mailing lists said change the cursor over every widget in the window: foreach widget [winfo children $window] { $widget config -cursor watch } To do this I'll need a list of

Dear list members, Is it possible via a suitable tcltk command to get the *current* width, in characters, of a Tk text widget that has been resized with the mouse? In the following code, the reported width of the text widget doesn't change, even though it has been resized. I can, however, get the current width in pixels: > library(tcltk) > top <- tktoplevel() > textWindow <-

Hi, I've been playing with the tcltk package. It's very nice to have access to buttons, menus etc. now. Thank you! Alas, I also have questions: In Tcl everything is a string [*]. This is not the case in R, of course. So why are return values of tk commands still strings? (Is there any other reason than speed or "package is work in progress"?) Example: > tt <-

My fame package has to link to the libchli.so that comes with FAME. However, FAME is now supplying both 32 and 64 bit versions of the library. The 32-bit version is $FAME/hli/libchli.so while the 64-bit version is $FAME/hli/64/libchli.so. To set the right flags, it seems that I need to know, from within configure.ac, whether the R installation is 32 bit or 64 bit. Is there a way to detect this?

When should we use one versus the other? If I'm designing an S3 class "blah", should I just implement blah <- function(x, ...) UseMethod("blah") and then a bunch of blah.whatever() functions, including blah.default()? Or should I do as.blah <- function(x, ...) UseMethod("as.blah") with a bunch of methods for it? Or do both?

I have a few functions, such as screenWidth() and screenHeight(), which I have been able to implement for a Unix/Linux environment, but not for Windows. (Does anyone know how to find the screen dimensions in Windows?) The Writing R Extensions manual tells me how to include platform-specific sections in documentation, and even how to have platform-specific help files. But it doesn't say

In Splus, I often use graphics windows with a black background and white foreground. The S print.graph() function sends the current plot to my printer but with a white background and black foreground. I'd like to be able to do something similar in R, but can't figure out how. I've tried various permutations of dev.copy() and dev.print(), but it seems that the foreground color is

Hello. This is my first post, so allow me to introduce myself. But first, I'd like to thank all the authors and contributors to the R software, as I think that it is truly a great and very useful package. I am the author of moodss, a GPL modular monitoring application (http://moodss.sourceforge.net). Moodss collects, archives in a SQL database and displays data from monitored devices,

I am the maintainer of the 'tis' package. One of the functions in my package is 'nberShade'. A user wants to make nberShade generic, with the old version renamed as nberShade.default, all of which is fine with me. And he wants to add a new method, nberShade.ggplot, which works for objects of class ggplot. He also wants to add a method fortify.tis for the generic fortify defined
