Everyday R: tips and tricks for data science with R

 COVID-19 vaccines do not work against Delta   Our hospitals are full with vaccinated patients   I'd rather wait for an inactivated vaccine   Two third are vaccinated and there's a lockdown again...   I've got my jab and got CoV afterwards, what a junk (des isch a Klumpert)!   I wear a mask, keep my distance, go testing, why I should let me vaccinate with this poison?!   Heard on the street, playgrounds in Tyrol and seen in social media in Austria these days.     Daily incidences breach every record, breakthrough infections rate climbs toward 50%, the national health care is approaching a collapse, the surprised government seems to have no idea... Hey, but two-third Austrians are fully vaccinated, what went wrong? The politicians claimed: the pandemic is over, CoV is gonna be an individual medical problem, it is this a pandemic of unvaccinated.   This motivates me to write this post. Does the anti-SARS-CoV-2 vaccination works against the...

It's again a while since the last post and almost two years of pandemic. Sadly said, a misery which would have been already over, at least in the first world, provided a better vaccination readiness of the US and European societies and more courageous political decisions. Frankly speaking, none of us is the same kind of a woman or men as before the SARS-CoV-2 crisis. Besides the real threats to our somatic health, there's another facet of human well being less prominently addressed by media news and scientific publications: mental health. Fear, paranoid feeling of being locked up, overwhelming concerns about own and family health, household finances, kids without school, lost jobs... This all has been burdening us and now seems to be somehow over but not completely. Could we measure this impact on mental integrity? Could we find out the causes? Is there a way to identify people at risk of mental health deterioration early on and help them? The team of 'Health after COVID-19...

Since the last post (a while ago), many things happened: to the pandemic, which we can now effectively fight against, to the awakening world economy, the even warmer climate... But also to the blog author, who now pursuits a free-lance data scientist career ( https://www.daas.tirol/ ) - any time happy to crunch your exciting data! In the mean time, I spent days if not weeks with an extremely interesting project named simply ' Health after COVID-19 in Tyrol ', whose results, while still not 'properly' published, can be accessed as a preprint . Well, probably there's probably no single person who hasn't heard the term 'long COVID', either from media, friends or relatives - a phenomenon of symptom persistence long after the acute SARS-CoV2 infection ranging from an isolated smell disorder to debilitating shortness of breath making everyday life a hard struggle. Even though the condition follows the 'ebb and flow' pattern of broad public interest, th...

Before I begin, I probably need to declare that although I'm a great enthusiast of vaccinations and got a more or less complete list of shots in my life, none of the pharma companies nor Bill Gates have ever offered me shares, honoraria or even a free vaccination. In other words I'm entering this topic highly influenced by subjective opinions and conspiracy theories without any financial conflict of interest and do my best to present you 100% scientific data.   COVID-19 vaccination was promised to be the next topic - it was already a while ago, cause I'm involved in two huge COVID-19 human studies and didn't find enough time for my blog. But I hope, I can report on our, still highly confidential, results in the nearest future.   Initially I thought: let's discuss the principle of vaccination and particular drugs, have a look what was published about efficacy and safety and, finally calculate, if getting an anti-SARS-Cov2 shot is worthwhile. But, I didn't expect ...
