Hi, I am Jens, aka Projectfreak. First, thank you all, for this forum. I already enjoyed the result of the question asked. Second, never really much of a programmer/developer, I've realised that approaching data science, ML and the likes as a project/program manager, requires you to know something about Python. R is likely next. I am a bit surprised how Python captured my interest, allowing me to approach data analysis through more powerful ways/tools. Although there is still a long way to go, I also must recognise that there is no turning back, and that one is never too old to initiate upgrades of skills and competences. Thank you, for your patience. I am looking forward to answering other people's questions one fine day.
