Require of gWidgetsRGtk2 fails: RGtk2.dll can't be found, but it's there

Dear list,

I've been trying to get gWidgets/gWidgetsRGtk2 to run every other month for
a while, but somehow I simply can't figure out what's going wrong.

Dear list,

I've been trying to get gWidgets/gWidgetsRGtk2 to run every other month for a 
while, but somehow I simply can't figure out what's going wrong.

I tried several distributions of the GTK runtime environment for Windows 
(http://downloads.sourceforge.net/gladewin32/gtk-2.12.9-win32-1.exe as 
described in the package's vignette, 
http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.1-20101227_win32.zip)

I also included GTK in my Windows PATH.

Yet, when I run 'require(gWidgetsRGtk2)', R complains that the RGtk2.dll 
can't be found/loaded (see below). But this file definitely exists. I'm 
running R-2.13.0 from a USB Device but made sure that args 'destdir' and 
'lib' are set propperly in 'install.packages'.

      Your subject line indicates your confusion.? It does not say
      RGtk2.dll cannot be found (at least, the English version of the
      message does not say so).

      What it means is that RGtk2.dll or one of the DLLs it depends on
      cannot be found.? See the instructions at
      http://cran.r-project.org/bin/windows/contrib/2.13/@ReadMe

      It is Microsoft's error message, not ours.


Thanks for your answer. I followed the advice in the readme file and installed

http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.22/gtk+-bundle_2.22.0-201010
16_win32.zip
Previously I made sure that all other previously installed GTK+ runtime
environments were removed and that the windows PATH reflects the correct path to
the "new" GTK+ files. I also made sure I started a new R session before trying
'require(gWidgetsRGtk2)' again. Yet, the same error. More precisely, a dialog box
pops up asking me to install GTK+ or not. That's what's confusing me as well: the
package's recommendation with respect to the version of an GTK+ runtime
environment is somewhat out-of-sync with the advice in the readme, even though it
the version is fairly recent (2011-04-30)

Sorry for the german part in the error message, but I wasn't able to get it all
to English (tried language = en in Rconsole file, setting up a Renviron.site with
LANGUAGE=en, setting Sys.setenv("LANGUAGE"="en") and Sys.setenv("LC_ALL"="en") to
no avail; not a good R day today ;-)). I freely translated it for you:

Do you have any other idea what I might be doing wrong?

1. Use the automatically installed GTk2, not some other version.

Thanks for answering. I didn't even know there GTk2 already ships with R.
Prof. Brian Ripley linked me to the readme file with recommendations with
respect to an GTK2 distribution to use:

"What it means is that RGtk2.dll or one of the DLLs it depends on cannot be
found.? See the instructions at
http://cran.r-project.org/bin/windows/contrib/2.13/@ReadMe "

2. Note that the automatically installed one will be at
...\GTk2-runtime\bin and that will be put at the *end* of your PATH.
Change it so that its at the beginning of your PATH to be sure its not
picking up something else.

My R distribution does not seem to have such a directory (standard windows
R-2.13.0 installer from CRAN)
How do I manage to have this ...\GTk2-runtime\bin directory available?

Thanks a lot,
Janko

3. If you are changing the path through the control panel and starting
R from the command line note that your new path won't be picked up in
old command line sessions so start a new command line session to start
R.

4. When you start a new R session double check that the automatically
installed ...\GTk2-runtime\bin is at the beginning of your path:

         strsplit(Sys.getenv("PATH"), ";")[[1]]

#1 is referring to the fact that when you run RGTk2 it will ask you if
you want it to install GTk2.  Say yes and let it install that version
to be sure you are using the right one.  If you install it yourself
manually instead you could very easily install the wrong version.

The only problem with the automatic installation is that it puts the
GTk2 dll's at the end of your PATH so you can't be sure that something
else on your path (such as graphviz which has its own potentially
conflicting dll's) won't interfere.  To fix that change the PATH so
that GTk2 is at the beginning (or at least before anything else that
could interere).

Thanks a lot,
Janko

3. If you are changing the path through the control panel and starting
R from the command line note that your new path won't be picked up in

It is a Microsoft error message, so your Windows is translating it, 
not R.  It does say 'The specified module' in English Windows, without 
saying who specified the module (but it does often produce a popup 
naming the module).

I've no better idea what your problem is: the @ReadMe instructions 
work for me, Uwe on winbuilder and in our teaching lab (and the advice 
in RGtk2 does not).
