[macosx] improving quartz & Aqua Tk behaviour outside of RGui
Hello,
On Mac OS X, certain Aqua/Quartz UI functionality requires an
application to be launched from within an app bundle, or
(alternatively) requires a Carbon application with a resource fork.
Playing with the wxWidgets distribution, I discovered that it is quite
easy and transparent to make such a Carbon app from (I guess) any
command line application. When applied to the R executable called

set tkscale by tkentry
Hi, I am working under Windows and I am using R2.11
I want to use tkscale in my GUI. As the interval is quite big, I can't set
the scale to a certain specific value. Therefore I want to add tkentry to
allow the user to set tkscale to a certain value.
Here is the code
library(tcltk)
tt<-tktoplevel()

Help with readBin
I'm trying to read a binary file created by a fortran code using readBin
and readChar. Everything reads fine (integers and strings) except for
double precision numbers, they are read as huge or very small number
(1E-250,...). I tried various endianness, swap, But nothing has worked so
far.
I also tried on R 64 bit for linux and windows (R 2.14) and R 2.11 on

Problem with geometry manager in TclTK
Hello, everyone.
I have the following problem with TclTk: I create some windows and want to
change their position with geometry manage (sometimes they will be centered,
sometimes not).
If the toplevel is created and its dimensions are gathered via 'tkwinfo', I
get (usually) correct values. However, if this window is created by a
function (in the following example, by 'ask.format')

Masked user input
Hi -
I'm creating a package of database tools. A function in the package
requires the username and password as input to the function in order to
initially connect to the target database(s). Of course, this poses a
significant security issue given the possible retention of the function
statement in cleartext. I did not readily encounter a package meant to mask
input from the user nor do I

Changing text in a tkentry widget
I searched the web and the list archives for a solution to this, but
didn't see anything, so here goes. I'm new to tcltk. I'm trying to

get that working, the widget will be read only to the user. Here is some

Question about unicode characters in tcltk
hello list,
Can someone help me figure out why the following code doesn't work?
I'm trying to but both Greek letters and subscripts into a tcltk menu.
The code creates all the mu's, and the 1 and 2 subscripts, but it
won't create the 0. Is there a certain set of characters that R won't
recognize the unicode for? Or am I input the \u2080 incorrectly?

Error in as.environment(pos): using 'as.environment(NULL)' is defunct
Hello,
I?m using R 2.11.1 with Tinn-R 1.17.2.4.
I hope the given informations are enough (it?s my first entry here)
The as.environment(pos) error appears in using the following code which

Here some extractions of the code:

fancier plotting
Hi
thank you for talking the time to help me with this.
I have a sequence of numbers in a file and an equal sequence of various character, say(a b c d) each occurs more than once. I need to plot the numbers so that numbers corresponding to a in the other sequence would have green dots, those corresponding to b a red dot, nothing on c and blue square for d. i.e
2 a show a green dot

How to use tcltk?
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:
