I have installed R-base backend it shows up in cantor and I can choose to create a worksheet with R backend, but again, it just shows the splash screen saying Initializing session and nothing happens. Refer to url for output of cantor_rserver. Reproducible: Always Steps to Reproduce: 1. Open Cantor 2. Select R Backend 3. Reproduced. Actual Results: Cantor's splash screen doesn't disappear Expected Results: Session should be initialized and user should be able to use R backend. This blogs refers to the problem http://blogs.fsfe.org/drdanz/?p=182 but I am unable to install ppa:daniele.domenichelli
R Backend is broken since several releases ago. We are trying to port the D-Bus technology implemented in R Backend to some standard streams communication technology like Q/KProcess. If someone has time to work on it, I and the Cantor community will be very grateful for the developer.

Git commit 4d570e46d2f1067d216f2bb067443623bec47716 by Filipe Saraiva, on behalf of Rishabh Gupta. Committed on 08/10/2017 at 08:00. Pushed by filipesaraiva into branch 'r-backend'. This change Ports R to make use of QProcess. Highlights of the changes are: * Disable R server * Make all the communication using QProcess (R's command line interface) * Plotting is supported by but plots are not integrated in the worksheet * Tab completion used to make use of RServer and hence it has been disabled for now Differential Revision: https://phabricator.kde.org/D7565 Close T6116 M +5 -4 src/backends/R/CMakeLists.txt M +1 -7 src/backends/R/rbackend.cpp M +0 -1 src/backends/R/rbackend.h A +16 -0 src/backends/R/rbackend.kcfg M +56 -21 src/backends/R/rexpression.cpp M +10 -7 src/backends/R/rexpression.h M +118 -83 src/backends/R/rsession.cpp M +17 -14 src/backends/R/rsession.h A +3 -0 src/backends/R/settings.kcfgc https://commits.kde.org/cantor/4d570e46d2f1067d216f2bb067443623bec47716
