Creating a sequence with full_seq()
The full_seq() function will look for the minimal and maximal values inside the vector you pass it and will then generate a full sequence of numbers with a fixed period in between them.
When used inside the complete() function, full_seq() is a handy tool to make sure there are no missing observations in your data. Before combining these two functions you'll generate a few sequences with full_seq() on its own to get the hang of this function.
