World Rugby has announced the match official appointments for the forty matches that comprise the Rugby World Cup 2019 pool stage (link).
Nigel Owens will referee the opening match when Japan play Russia at the Tokyo Stadium on 20 September.
There is an official list of all the appointments for the pool games (link).
There is a list of the twenty-three officials selected to officiate at the 48 matches at Rugby World Cup 2019 (link). There are twelve referees, seven assistant referees and four television match officials that represent nine nations.
Each day, Mara Averick (@dataandme) (link) shares some excellent R advice and links on Twitter. For a while, I bookmarked all her suggestions but there were so many of them that I did not manage to return to them. Even allocating them to bookmark folders did not improve my follow up rate.
For the past month or so, I have been creating R scripts in RStudio each day to try out the coding of some of her suggestions. This was the case today with her link to Joachim Gassen’s ExPanDaR 0.4.0 package (link).
I have a GitHub repository for this exploration to share my csv files and code (link). Like most of my efforts it is just a start … and an attempt to share sport examples.
However, I am really interested in the package’s potential for me to have a first look at data, and if appropriate to work through it with coaches to develop their data dashboard … if they think it can be of help to them.
I used the ExPanDaR’s functions to create: a descriptive table (of all variables); a scatter plot; a quantile_trend_graph (distributions of one variable over time); and a list of the 5 most extreme observations in the data frame. I particularly liked the Shiny opportunities I had to plot variables. I am still trying to work out the tooltip functionality for my descriptive table.
My visualisation examples are:
I am looking forward to exploring these functions and other visualisation functions available in ExPanDaR.
