Technical requirements

There are a few technical requirements for this chapter. Note that the code for this chapter can be found at https://github.com/PacktPublishing/Extending-Excel-with-Python-and-R/tree/main/Chapter%2010.

Some of the packages that we will be using in this chapter are as follows:

• healthyR.ts
• forecast
• timetk
• Modeltime
• prophet (for Python)
• keras
• tensorflow

We will start by creating time series objects in base R. The basic object class for a time series object in R is ts and objects can be coerced to that object by either using the ts() function directly or calling as.ts() on an object such as a vector.
