Map and Nested Lists

27 April 2022 On StackOverflow, a questioner with a bunch of data frames (already existing as objects in their environment) wanted to split each of them into two based on some threshold being met, or not, on a specific column. Every one of the data frames had this column in it. Their thought was that they’d write a loop, or use lapply after putting the data frames in a list, and write a function that split the data fames, named each one, and wrote them out as separate objects in the environment.

Indexing Iterations with set_names()

10 April 2022 As mentioned last time, we often want to build up a data frame iteratively. The map() family of functions in purrr can help with this.

15 February 2022 For the past view years, Jason Snell at Six Colors has conducted a survey of people who write about Apple. He asks a series of questions about the company and its products and presents a report of people’s answers. This year’s report has all the details for those interested. I’m a subscriber to Six Colors (it’s well worth it if you like that sort of thing). In the course of chatting about the report and its graphs in the member Slack, Jason kindly shared an anonymized version of the survey data with me.
