Hi everyone In case you're trying to use RKWard (GUI environment for the R language) on Linux Mint 19.1 and you keep getting the following error message: "The KDE installation could not be found (kreadconfig5). When moving / copying RKWard, make sure to copy the whole application folder, or create a shorcut / link, instead." Then simply install the following package: libkf5config-bin For instance, you can do this using apt-get: sudo apt-get install libkf5config-bin -- source: https://rkward-devel.narkive.com/M5x9XHCk/rkward-0-7-0-is-available Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
