A typical call to read_csv will look as follows. The only required argument to read_csv is a character string specifying the path to the file to read. The read_csv function also adds some nice user-oriented features like a progress meter and a compact method for specifying column types. R’s built in read.csv function similarly reads CSV files, but the read_csv function in readr builds on that by removing some of the quirks and “gotchas” of read.csv as well as dramatically optimizing the speed with which it can read data into R. The importance of the read_csv function is perhaps better understood from an historical perspective. The readr package is available on CRAN and the code for the package is maintained on GitHub. The readr package has a few functions in it for reading and writing tabular data-we will focus on the read_csv function.

The readr package is the primary means by which we will read tablular data, most notably, comma-separated-value (CSV) files.

Read tabular data into R and read in web data via web scraping tools and APIs.
