pepper | R Documentation |

Given a list of variables, construct every term comprising only those
variables; function `pepper()`

returns a free algebra object
equal to the sum of these terms.

The function is named for a query from an exam question set by Sarah
Marshall in which she asked how many ways there are to arrange the
letters of word “pepper”, the answer being *6!/(1!2!3!)=60*.

Function `multiset()`

in the `partitions`

package gives
related functionality.
