Just updated R and RKWard and i'mhaving problems starting the GUI. Running rkward from the terminal i get the following:
KCrash: Application 'rkward' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
 Exit 253 rkward
+ Stopped rkward
Below is the error stack
What should i do to fix it?
I was just going to tell you to re-compile RKWard after udgrading to R 3.0.0, but in fact, your backtrace looks different.
I have found a bug that might be causing this in SVN, and fixed it. If you are building from SVN, please try again after an "svn up".
Otherwise, this problem may occur, if a "pluginmap" which was previously known to RKWard can no longer be found. You can check your ~./kde/share/config/rkwardrc for such pluginmaps, and remove them manually, or (re-) move ~./kde/share/config/rkwardrc to start with a clean setup.
However, quite likely, the reason that a previously known pluginmap file has gone missing, is that you did not install RKWard, correctly. In particular, make sure to use the correct -DCMAKE_INSTALL_PREFIX option when compiling. Note that binaries of RKWard for Ubuntu and R 3.0.0 are available since yesterday: https://launchpad.net/~rkward-devel/+archive/rkward-stable-cran .
Finally: Please don't post to both the forum and the bug-tracker. Either would have been fine in this case, but having both just increases the bookkeeping effort.
Thanks for your answer and sorry for double posting.
I managed to install it by adding the new ppa and then
sudo apt-get install rkward.
Hi, I get the same error. I have installed the RKward package from launchpad (CRAN version) through the ubuntu software center (previouslly I added the ppa:rkward-devel/rkward-stable-cran to my system)
The output of rkward --version is:
Plataforma de desarrollo de KDE: 4.8.5 (4.8.5)
File rkwardrc does not exist.
Thank you for any help!!
The error output at the starting point is attached.
I'm not sure this is the same bug. The last two stops of the backtrace look the same, but not what leads up to it. Before anything else, please double check:
a) That you have R version 3.0.0 installed, i.e. not the version of R that came with your Ubuntu, and that R 3.0.0 is at /usr/bin/R. If /usr/bin/R is the version that came with your Ubuntu, use the "rkward-stable" PPA, not "rkward-stable-cran".
b) That you really do not have an existing ~./kde/share/config/rkwardrc .
c) That 'which rkward' shows /usr/bin/rkward (i.e. there is no confliciting installation on your system).
If none of this is the issue, start rkward with "rkward --debug-level 5", and post the latest pair of /tmp/rkward.frontend.XYZ and /tmp/rkward.rbackend.XYZ after that.
Addendum: Of course R 3.0.1 is ok, too.
Thank you Thomas for your quick answer.
When I started to check the 3 points, I discovered the file "rkwardrc". I changed its name, and all worked fine!!
The problem was:
I used RKward stable ubuntu version, with R 2.15. But when R 3.0.0 (CRAN) stable version was released, the RKward 0.6.1 from lunchpad did not work (an error about dependencies prevented the installation). I had to move to RKward CRAN version. I checked "rkwardrc" after compiling the wrong version of RKward (launchpad.net/~rkward-devel/+archive/rkward-stable), so I never got the file. But now, with CRAN version ("launchpad.net/~rkward-devel/+archive/rkward-stable-cran") I found the file. I've renamed it, and thats it!
Thank you for your help!!
