One weiRd tip Cut the time it takes to analyse data

Small intro

Assuming you’ve got RStudio installed and open, we will install some extra packages that extend the functionality of R.

install.packages(c("ggplot2", "openair"))


The above code blocks will install and load the following libraries (and their dependencies):

  • ggplot2, a powerful plotting library that uses a grammar of graphics
  • openair, a collection of useful tools for analysing air quality data

The openair library contains a dataset called mydata, which we will use to demonstrate the use of R. This data was collected from 1 January 1998 to 23 June 2005 at the Marylebone (London) air quality monitoring station.

We’ll use the data command to tell R to load the dataset and use the ggplot2 library to visualise our data.

ggplot(data=mydata, aes(x=date, y=pm10)) + geom_line()
