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!
