Details

R has a limited number of built-in constants (there is also a rather larger library of data sets which can be loaded with the function data).

The following constants are available:

• LETTERS: the 26 upper-case letters of the Roman alphabet;

• letters: the 26 lower-case letters of the Roman alphabet;

• month.abb: the three-letter abbreviations for the English month names;

• month.name: the English names for the months of the year;

• pi: the ratio of the circumference of a circle to its diameter.
