read_tsv

Where you use read_csv() to easily read in CSV files, you use read_tsv() to easily read in TSV files. TSV is short for tab-separated values.

This time, the potatoes data comes in the form of a tab-separated values file; potatoes.txt (view) is available in your workspace. In contrast to potatoes.csv, this file does not contain columns names in the first row, though.

There's a vector properties that you can use to specify these column names manually.

Anleitung zur Übung

  • Use read_tsv() to import the potatoes data from potatoes.txt and store it in the data frame potatoes. In addition to the path to the file, you'll also have to specify the col_names argument; you can use the properties vector for this.
  • Call head() on potatoes to show the first observations of your dataset.
