The R programming language was designed by statisticians and was specialized for statistical computing. It is often regarded as the most important programming langauge for statistical analyses, but is also extremely useful for any type of data analysis. Many people want to learn R to gain skills for a career in data analysis.
Learning any programming language can be daunting for beginners, and there is no doubt that it will take a lot of time and lots of practice to develop skills for deep data analysis. Nevertheless, learning even the basics of R will allow beginners to perform simple data analysis such as visualizing data, make calculations, and performing statisical analysis.

Why Learn R?

Just how many people are there by age group in Ireland?
Many people in Ireland and all over the world are anxiously waiting their turn to receive the Covid-19 vaccine. In Ireland we have 15 groups in our HSE priority list for the vaccine. As a 61 year old, I fall into the 12th group ("People aged 55-64"). There are no dates yet for when this group will receive the vaccine. The list is based (fairly in most people's view) on vulnerability and age. This got me thinking about how many people there are in different age groups in Ireland.
The Central Statistics Office provides Census data for 2016 - the most recent available. The population of Ireland in this census was 4,761,845, and data is provided by five year age groups. Using Excel I plotted these data in a bar chart.

First, I was struck that the age ranges were not evenly balanced. The highest age group are in the 35 to 39 age range, while the lowest is the over 85s. In my own age group (60-64), I am one of 238,856 people. To vaccinate everyone over 65 (priority #5 on the HSE list) means that 570,012 will get the vaccine ahead of the rest of us. According to the 2016 census, there are only 67,555 people over the age of 85 (which includes my Mum and Dad) - this should now be an easy and quick group to vaccinate. If you are in the last group ("People aged under 18 and pregnant women", #15 on HSE list), then there are approximately 3.5 million people ahead of you in the vaccine queue.

Resisting Temptation to go back Lecturing
Recently, I turned down the opportunity to lecture some modules this coming semester at a College that I had not worked with before. I was flattered, but also very honoured to be asked. The modules did not quite suit me so it was an easy decision to say "no". Even if it was just a little bit - I was slightly tempted to give it a go.
Given that many of the things I had planned to do during retirement will not be possible for the next few months, it might have been a good use of my time to take on a module or two. I had said "no" to joining the Associate Faculty of part-time lecturers in my old College as I did not want to be tied down during a 12 week semester. I wanted the freedom to come and go as I please, and having classes every week would interfere with this.
I'm wondering how many others who have retired during the Pandemic feel a little cheated and feel they might be better of back at work? Us retirees are all looking for things to do. I am recording a lot of videos for YouTube release and spending time building up my family tree. I'm also watching a lot of Netflix!
I don't see myself going back to part-time teaching. Hopefully we will all be vaccinated before the end of the summer, and my retirement can really begin!

New YouTube video: "How To... Download and Insert a YouTube Video into PowerPoint with Mozilla Firefox"
In August 2019 I received the following Channel Violation message on my YouTube Channel:
Eugene O'Loughlin, your content violated YouTube's Community Guidelines and has been removed
The video was about how to download videos from YouTube using Mozilla Firefox - originally published on 23 October 2013. At the time I was genuinly shocked that I had allegedly violated some rule and I was very surprised that it took five years for this happen. I appealed the decison, but was rejected. It turned out that I was guilty of posting content that encouraged other users to violate YouTube's Terms of Service. Towards the end of the video I stated that downloading a video was a good way to avoid ads. Guilty m'lord!
The Channel Violation message is still located at the top of my Channel page. Before the video was taken down it had amassed 89,918 views, 177 Likes, and 15 Dislikes. I checked today if there are any other videos that show how to do the same thing, and there are hundreds. So I have decided to re-record without the "encouraging other users" message (I did this last year), and upload again. Fingers crossed that I have not violated any further rules as this would be my second strike - YouTube operates on a "three strikes and your out rule".

Fr Theophilus Murphy OFM
Over the past few months I have had the time to do a lot of research into my family tree, and one of the more interesting ancestors that I have is Fr Theophilus Murphy. When I was growing up, there were many mentions of a "Fr Theophilus" and "Rhodesia". I have vague memories of him calling to our house in Ballingate.
