Learn together: Iterating well with purrr

Description:
This is an in-person, informal, facilitated session to learn together.
Bring a laptop with R and RStudio installed to participate. The topic is geared towards folks with R experience, but all are welcome.
Refreshments (pizza and soda) will be provided to fuel the learning.

The learning objectives:

• Describe drawbacks of copying and pasting R code.
• Complete tidyverse style code with the pipe operator (`%>%`).
• Accomplish iteration through vectorized functions.
• Leverage `group_by()` as an iterative technique.
• Explain differences between base R and {purrr} iterative functions.
• Explore lists as an object to store information of varying types and sizes; explain how to extract elements from a list.
• Apply functions from the `purrr::map_` family to perform iteration as an alternative to loops.

COVID SAFETY. Because the pandemic is not over yet, we have a few requests in order to keep everyone safe:

• Please do not come if you are not fully vaccinated (we look forward to seeing you in person as soon as it is safe for everyone to resume normal activities, though!)
• Follow CDC and Philadelphia guidelines on COVID safety
• Bring a mask and wear it when required by the location
