When I connected my phone to my Kubuntu laptop using a USB cable I experienced an astonishing phenomenon: Opening up a Dolphin (file manager) window I could easily navigate to it, browse the whole directory contents, but when I tried to get there via commandline I had no chance at all! Same for Double Commander,…

The fabulous Atom editor lacks one feature out of the box, and that is a developer’s cycle for compiler languages (or similar applications). Compared to Visual Studio Code it’s exactly one thing missing: Build/compile and run in a console window which is part of the IDE! Okay, Atom is no IDE! At least not in…

The first thing I came across was how to construct a hexagon in R. After I figured out how to define one and how to plot it, the next idea was to animate it. And this is the source code: # Hexagon —————————————————————- # Activate plot window prior to start # Aspect ratio can be…

First, on Linux Mint 20 the installation of Rcmdr is no problem at all. But on Kubuntu, it is. When you try to install Rcmdr from within RStudio by install.packages(“Rcmdr”) you may run into the error msg: Error: package or namespace load failed for ‘tcltk’: .onLoad failed in loadNamespace() for ‘tcltk’, details: call: fun(libname, pkgname)…

The following recipe is applicable to a machine (maybe a virtual one) running under Kubuntu 20.10 Desktop, but may be helpful for other Linux distros, too. In order to brush things up for Google: We are talking about ./configure, make, make install of R (r-project.org) and installing RStudio (rstudio.com) on a Linux computer. One advice…

I’m sure that you will encounter problems when you fire up your new Kubuntu 20.10 Desktop virtual machine under the impression things would work out fine with just giving the VM the ISO file with these additions.
