Hi!
I've trying to plot data that has been mutated into quarterly growth rates from nominal levels.
i.e the original dataset was
| Date |
GDP Level |
| 2010Q1 |
457 |
| 2010Q2 |
487 |
| 2010Q3 |
538 |
| 2010Q4 |
589 |
| 2011Q1 |
627 |
| 2011Q2 |
672.2 |
| 2011Q3 |
716.4 |
| 2011Q4 |
760.6 |
| 2012Q1 |
804.8 |
| 2012Q2 |
849 |
| 2012Q3 |
893.2 |
| 2012Q4 |
937.4 |
Which was in an excel file which I have imported using dataset <- read_excel("xx")
Then, I have done the below in order to mutate it to quarter on quarter growth ("QoQ Growth):
dataset %>%
mutate(QoQ Growth= (GDP Level) / lag(GDP Level, n=1) - 1)
I would like to now plot this % growth across time, however I'm not too sure how what the geom_line code is for a mutated variable, any help would be really truly appreciated! I'm quite new to R and really trying to learn, thanks!
