...the left button of the mouse. How can I determine the mouse position without any click? Is it possible to extend locator in a way that locator(n=0) outputs the coordinates at once, without any click event? TclTk allows us to define very nice animations and demonstrations, see for example: demo(tkdensity). But sometimes it is much better to have output and control in one window and to be able to respond to changes of the cursor position (e.g. to that a bandwidth).

Dear R-Users I'm running SuseLinuxPPC 7.1 and R 1.2.3 installed by sources. I've tried to run the demo for Tk (tkdensity e.g.) but R says " > require(tcltk) || stop("tcltk support is absent") Loading required package: tcltk Error in firstlib(which.lib.loc, package) : Tcl/Tk support is not available on this system Error in eval.with.vis(expr, envir, enclos) : tcltk support is absen...

Friends: I have a tcltk widget for inputting constants and other values that are needed by subsequent R functions. My widget works well. I have an OnOK function that does what I had hoped it would. Among other input items the widget also uses 6 radio buttons to select one of 6 choices. It functions as it should. Here is the problem: I would like one of the buttons to be the default and to

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 --vanilla > library(tcltk) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "C:/PROGRA~1/R/RW1041/library/tcltk/li...

...e tcltk package, to a simple gui. My search for R code which utilizes these two functions has come up empty. Currently, I am attempting to translate pure "Tcl/Tk" code to R with little to no success. So far, the most helpful tool for learning the tcltk R commands has been the "tkdensity()" and "tkttest()" examples, included in the tcltk package. Any other (simple) examples of gui construction utilizing the tkmenubutton() or tklistbox() functions would be greatly appreciated.

...t calling tkStartGUI. I switched back to 10.2.6 and it works as well. I think this is due to the "last minute" fix in RAqua now using idle timers because of too much cpu usage. Some "mouse" trick is needed though. If you want to test it you can just try library(tcltk) demo(tkdensity) press return and wait for quartz device to show the density plot. Then to interact with the widgets just click outside R (everywhere but not windows related to R) and click on the tk-window to activate it. Now you can interact with the widgets for "some time", which means that after...

...uaTclTk. http://www.economia.unimi.it/R/RAquaX11.dmg (15 MB disk image) The idea is that you: launch RAqua, launch X application (the X Server), and from inside R type x11() # just tt set DISPLAY to :0.0. Eventually close this window device, we don't need this. load(tcltk) quartz() demo(tkdensity) It works on my Panther machine as well and it comes with three installers for: libreadline, tcltk (the X11 version) and the libxml2 in case you want to use the prebuilt XML package. Thomas Lumley has found oddities in configuring/building R on Panther so I built it on Jaguar and it works as...

...(NULL) (170.54.59.160) In the R windows FAQ, item 3.6 (Package TclTk does not work) currently has this line: Sys.putenv("TCL_LIBRARY"="c:/Program Files/Tcl/lib/tcl8.3") I find that if I execute the following two lines after starting R, I can then do library(tcltk) and demo(tkdensity) as usual. I do not need to modify my autoexec.bat this way! Anyway, using the following two lines in the FAQ might be useful to some people.

...rtz device or with native tcltk, because the windows do not accept events (cannot be brought to the front). I know why this does not work (Terminal.app is the frontmost application and it does not know anything about those windows). IDLE/Rpy with R-devel can do some of the tcltk demos (tkcanvas, tkdensity, tkfaq) but not all (tkttest,tkfindfile). And, surprisingly enough, IDLE/Rpy with R-patched can do the same demos (and fails on the same demos), although its tcltk is compiled using fink's X11 based tk. No X server is running in these cases. I have no idea why some demos work and others don...

I was a bit suprised to note that demo files are not run as part of R CMD check. This seems out of keeping with the philosophy of running all code contained in the package (in the source, in examples etc). Should demo files be checked as part of R CMD check? Hadley

Hallo Tk experts, the Tcl/Tk package allows to define very nice widgets for starting R functions, for printing results and for interactive parameter input. tkdensity.R and tkttest.R demonstrate this and both demos explain how some of the tk functions can be used. For constructing new widgets I would like to see further examples showing Tcl/Tk package in action. Therefore my question: Is there a pool of well designed applications of tk functions? / Have you crea...

Hello, I need to design a fairly simple front-end for someone to use an R script system that I've built. My thought was to just use the text based menus available in the base R package, perhaps in some kind of loop. How have other people done this? Any "best practices" that you can recommend?

Dear R users, I'm working with Windows 2000 and R -- note that I could maybe work with Linux too... I would like to know if it is possible to build a stand-alone statistical package which: -- could be programmed in R language, -- could have a nice graphical interface with buttons and menus (this package will be distributed to non-statistician people), -- could realize statistical operations,

Dear anybody dealing with TCLTK on R I'm trying, without any success, to get a simple TCLTK window to remain floating on top of the RGui and RConsol windows when the later have focus. I cannot find reference in the TCKTK documentation and fear that I'm missing something quite fundamental. My objective is to make a simple button populated menu to invoke R functions. I wish the TCLTK menu
