read_delim
Just as read.table() was the main utils function, read_delim() is the main readr function.
read_delim() takes two mandatory arguments:
file: the file that contains the datadelim: the character that separates the values in the data file
You'll again be working with potatoes.txt (view); the file uses tabs ("\t") to delimit values and does not contain column names in its first line. It's available in your working directory so you can start right away. As before, the vector properties is available to set the col_names.
