read.delim

Aside from .csv files, there are also the .txt files which are basically text files. You can import these files with read.delim(). By default, it sets the sep argument to "\t" (fields in a record are delimited by tabs) and the header argument to TRUE (the first row contains the field names).

In this exercise, you will import hotdogs.txt (view), containing information on sodium and calorie levels in different hotdogs (Source: UCLA). The dataset has 3 variables, but the variable names are not available in the first line of the file. The file uses tabs as field separators.
