Importing data is the very first step!
You can use readr to import rectangular data.
You can import…
- comma separated (CSV) files with
read_csv() - tab separated files with
read_tsv() - general delimited files with
read_delim() - fixed width files with
read_fwf() - tabular files where columns are separated by white-space with
read_table() - web log files with
read_log()
