Tcltk question for R people
Hello...
Curious to know whether the TK extensions “Tktable” and “Iwidgets” will be
included in future versions of R (full installation). These are key
components of GUI construction and would be very useful in my current
R-tcltk endeavors. I realize that I could just install a version of
ActiveTcl, which includes the extensions; however, my goal is to eventually
distribute my work keeping

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
4 b show a

tkentry that exits after RETURN?
I can set up an entry widget (thanks to an old
post by Barry Rowlingson) that gets a password and
exits when the user clicks on the "OK" button.
Anyone have any clever ideas for returning/
destroying the window when the user types a carriage
return/ENTER in the text window? I've messed around
a little with validate, validatecommand, but don't
see any obvious way to do it ...

rerender tcltk toplevel
Hi everybody,
I am trying to write a simple progress display based on a tcltk
toplevel. My first approach was to use the progressBar widget from the
BWidget library but since this is not available on every system (missing
on at least almost all windows systems, I guess...) I wanted to have a
backup there. So my second strategy was to use a simple toplevel with a
label and update the tclvariable

[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

Me again, about the horrible documentation of tcltk
How on Earth can I know what are the arguments of any of the functions of
the tcl/tk package? I tried hard to find, using all search engines
available, looking deep into keywords of R, python's tkinter and tcl/tk, but
nowhere I found anything remotely similar to a help.
For example, what are the possible arguments to tkgetOpenFile?
I know that this works:

smooth scrolling with windows() function
Hi,
I have a large plot that I would like to display in a graphics device with
scroll bars. I therefore decided to use the windows function like so...
mag<- length(tick)
windows(height=mag/8, width=10, rescale="fixed")
However, when I use the scroll bars the device (i guess) is re-drawing the
plot. Is there any way in which I can get it to 'smooth scroll'?
Kind regards,

Windows, OSX and Linux: updating a graphic device and double buffering
Hello there,
I'm struggling with the base graphics system on different
operating systems.
I would like to get an animation effect by re-plotting with the plot
function. See the attached code example: move the slider
quick from one side to the other.
I experience different levels of success, depending on which OS I use.
