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
should open a function in an other R-file.
Here some extractions of the code:
....
HZ<-tclVar(seq(length=a,from=1,by=0)) #(a is defined by a
tkentry-element)
VZ<-tclVar(seq(length=a,from=1,by=0))

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 ...

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

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')

R tcl/tk
Friends:
I am a long-time R user, learning tcl/tk, and am tying myself in knots over
something that should be simple.
I want to create a frame and put that frame inside the toplevel frame.
This works (i.e. it places text in col 1, and the corresponding entry box in
column 2) and later frame.2 resides where it should in the toplevel frame.

[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

read.table in TCL/TK interface

the t-test example in a more complex way !

(I'm newbie and take code-parts from t-test example and scripting example.)
(2) Is it possible to use a variableSelection widget
to select a special variable which i
