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
windows XP 32 bit.

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 ...

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

[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

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?

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.

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
change the contents of a tkentry widget when a button is pressed. Once I
get that working, the widget will be read only to the user. Here is some
toy code:

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)

Building tkentry dynamicly
Dear R-users,
I would like to build N "tkentry" compounds in the same window, with
default text for each. As N is variable I need to construct them in an
iterative way :

main<-tktoplevel()
tktitle(main)<-"My Tool"
filenames<-c("toto","tata","titi")
N<-length(filenames)

Retrieving data from a tcl /tk function
Hello,
I am sorry if this is an answered question, but I did my homework for a long while and couldn't figure out a way to retrieve data entry from a model dialog. In one of the examples compiled by James Wettenhall:
odalDialog <- function(title, question, entryInit, entryWidth = 20,
returnValOnCancel = "ID_CANCEL") {

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)

disappearing dialog boxes when using tcltk
Dear all,
I'm trying to use tcltk to build a small
user-interface and couter the problem:
It seems that sometimes the dialog box will be
minimized automatically though I want it to be on top
of the screen all the time.
For example, when runing the following code, if you
type in "a1", "a2", "a3", etc when being asked for an
integer, the program is supposed to

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')

tcltk in BATCH mode
DeaR list,
I am writing a user friendly script for an interactive use of R. The user is
supposed to click on a bat-File in Windows-environment and to enter some
values in a pop-up window.
Let us assume we have the script given below. If she sources this script
within R, everything works smoothly. The pop-up window jumps and patiently
waits her to enter the value. For this to work she has to start

Dropdown boxes in tcltk and R
Hello,
I'm very much a newbie in R and more so in tcltk so apologies if this
question is stupid. Basically I am trying to use the combobox example
found here:

What I want to do is in that example get fruitChoice as a variable in R
in general. When I run that code, however, and the ask for fruitChoice
