Just getting started with R so quite unfamiliar, I've got a dataset that looks like this:
Essentially, I have been able to plot each year on the x and each corresponding level of GDP on the y
However, I was wondering how to plot:
quarter to quarter % growth: i.e. gdp growth rate for (2012Q3-2012Q2)/2012Q2
year on year % growth: i.e. gdp growth rate for (2012Q3-2011Q3)/2011Q3
just not really sure how to ggplot % changes, really trying to learn R but finding it hard, any help would be greatly appreciated!
