Import multiple files from a local file system: iterate functions [Rfun]

Ingest multiple files from a local file system: iterate functions code available at https://github.com/libjohn/workshop_rfun_iterate full video series -- playlist --https://www.youtube.com/watch?v=PrUnbYlC1kY&list=PLIUcX1JrVUNWW7RgPh9ysmJM3mBpIAlYG Using the case-study of data cleaning, this modular video series will demonstrate iteration with `purrr::map()` and custom functions while also showing several Tidyverse tips and tricks. This individual video (1-A) in the series uses the basic proposition of importing multiple CSV files. Each #IterateFunctionsR video will become progressively more fluent, using building-blocks to present intermediate data manipulation techniques in R and the Tidyverse. By the end of the series you'll learn how to use the purrr package, a very convenient package in support of iterating over list-columns and nested data frames. purrr::map() iteration is often more convenient and efficient than a For-loop. You'll also learn how to compose custom functions in R. since R is a functional programming language, composing your own custom functions can increase your fluency as an R coder.
