Pipes in map()
So you've refreshed your memory on how pipes can be used between functions. You can also use pipes on the inside of map() function to help you iterate a pipeline of tasks over a list of inputs.
Here instead of using one of the repurrrsive datasets, you will be working with a list of numbers so that you can do a few mathematical operations.
Deze oefening maakt deel uit van de cursus
Foundations of Functional Programming with purrr
Oefeninstructies
- Create a list that contains the values 1 through 10, each as a separate element.
- Create a pipeline within one
map()function that takes thesqrt()of each element, and then thesin()of each element.
