R Overview of the Month
This month at UQRUG, before we jump into our help session for everyone to ask questions, this month Nick will look at how we can use some preliminary exploratory data visualisations to identify data issues using the visdat package.
You can download the R file here and then convert it to Rmd after downloading.

Q3 - Jayne - Plotting two lots of data on one graph and splitting by time
- regarding plotting of two lots of data on the one graph
- plus splitting the graphs into smaller time lots
Answers
Plotting two y axes * reminds me of some data I had analyse … correlating events with denser sets of points
- This site has details for plotting a ggplot2 graph with two y axes: https://r-graph-gallery.com/line-chart-dual-Y-axis-ggplot2.html
Splitting data by time * Create a new variable that gives a value to each “block” of time and create the facet wrap on that * Perhaps using the Lubridate function hour() to extract the hour into a new column
