Is the tcltk failure in affylmGUI related to R bug 15957
I maintain the package affylmGUI. It works when installed on many
previous versions of R. I have today tested exactly the same code under
R-2.15.3, R-3.0.2, R-3.1.0, R-3.1.1, R-3.1.2 and R-devel.
I have also tested the versions of affylmGUI downloaded by biocLite for
each version of R and the same result applies.
I have no errors under 2.15.3, 3.0.2, 3.1.0 and 3.1.1. The following

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:

I'm posting yet another question about tcltk since I'm still struggling
with the package. I'm trying to create a tklistbox and a ttkcombobox on
the same parent and am having a problem. Here's an example:
library(tcltk)
tt <- tktoplevel()
tcl1 <- tclVar()
tcl2 <- tclVar()

tk problem with R 2.2.0 on wine/linux
Actually I am trying to run sciview-R and encounted some problems with
tk, and I thought I'll check the basic library(tcltk) functionallity,
just to be sure. Anybody seen that '[tcl] bad window path name ".1".'
message before?
Prof. Philippe Grosjean: yes, I have managed to load most of
sciview-R under Wine, except the tcltk library!

tkinsert (PR#4289)
In R-1.7.1, I used to be able to append a character vector to a 'tklistbox' with e.g.
listio <- tklistbox( tktoplevel(), font='Courier', height=20, width=20, setgrid=TRUE)
tkinsert( listio, 'end', letters[1:3])
tkpack( listio,side='left', expand=TRUE, fill='both')
and three items would be added to 'listio'. This doesn't work in R-devel-- it

Using tcltk to display jpeg images
Dear R Helpers,
Does anyone know how to use tcltk to display jpeg images? The manual says
that
one must use Tk_PhotoCreateImageFormat to register the jpeg image handler.
The
"ActiveTcl User Guide"
(http://support.serv.ch/lang/tcl/img/doc/img-jpeg.html)
says:-
"The package img::jpeg is a sub-package of Img. It can be loaded as a part
of the complete

Is the tcltk failure in affylmGUI related to R bug 15957
Seems unlikely that that particular bug is involved. I seem to recall some change related to inadvertent variable capture in .TkRoot$env (?). At any rate, we currently have
> parent.env(.TkRoot$env)
<environment: R_EmptyEnv>
which used to be
> parent.env(.TkRoot$env)
<environment: R_GlobalEnv>
as a result, this won't work any more because R_EmptyEnv has no operators and

R and TK Error "can't find objects"
Dear R People,
I?m trying to link R and TK. I?m using R 2.11.1 with Tinn-R 1.17.2.4.
For simple examples like the following one it?s working (see the
initiation of the variables, the handler and the link to the function
which multiply Zahl, Exponent and Factor) :

Link R with Tcl 8.6 on Windows
Dear all,
I am working on an R package intended for CRAN that requires Tcl version 8.6 because of the TclOO tcl extension and the -angle option for canvas text items.
R for Windows currently still ships with Tcl 8.5. Does anyone have experience with linking R under Windows to a Tcl interpreter of version 8.6?

Is the tcltk failure in affylmGUI related to R bug 15957
Thanks Peter and Dan for your replies.
After learning a bit more about tcltk and environments etc. I have replaced
Try(n <- evalq(TclVarCount <- TclVarCount + 1, .TkRoot$env))
with
Try(n <- .TkRoot$env$TclVarCount <- .TkRoot$env$TclVarCount +1L)
as you suggest.
It now works for both R-3.1.1 and R-3.1.2+
(My understanding is that the Try function is there to put a GUI box
