‘dygraphs’ is a JavaScript library useable within R which allows for the creation of interactive charts. The package is particularly useful in this case because it is capable of plotting large datasets and representing that information in a way that is intuitive, easily understood and easy to manipulate (Dygraphs, 2023). For the purposes of this work, dygraphs will be used to represent monthly rainfall data obtained from four Irish weather stations over the period 1850-2014. This data is continuous over the period for which it was recorded and then offers a valuable resource for data analysis.
