Installing the official release

Installation of RKWard on windows should be straight-forward: Simply download and run the latest installer. The installer includes RKWard 0.7.2, R 4.0.2, and all required KF5 frameworks (version 5.64).

Please note that the installer may appear to “hang” around 70% completion. This is just a problem with the progress bar not updating. Please be patient.

For installing older, KDE4-based versions of RKWard, refer to the instructions an an earlier version of this page.

Installing development snapshots

Development snapshot are available from . Note that these are built, automatically, and provided without any human testing. Back up your data, before using these.

Updating R inside the RKWard installation

Since RKWard 0.7.1, updating R is often possible without any updates to RKWard, especially, for patch level releases of R (e.g. 4.0.3 over 4.0.2).

The recommended way to update R is to

  1. Install R as usual, in its default installation location.
  2. Open the file [Your\RKWard\Installation\]\KDE\bin\rkward.ini, and change the path for “R_executable” to either “auto” or the full path to R.exe.
  3. In case of any problems revert the changes to rkward.ini.

Alternatively, you can install your new version of R to [Your\RKWard\Installation\]KDE\libs\R. The potential advantage is that you will not have to reinstall your R packages after updating R (although it is still recommendable to do so).
