Performs the bootstrap t-test as described in Algorithm 16.2 in Efron and Tibshirani (1993).

1 | ```
boot.t.test(x, y, reps = 1000, mu = 0, alternative = c("two.sided", "less", "greater"))
``` |

`x ` |
Vector of values from the first group. |

`y ` |
Vector of values from the second group. |

`reps ` |
Number of bootstrap replications to use. |

`mu ` |
Null hypothesised difference between the group means. |

`alternative ` |
The alternative hypothesis to use (default = "two.sided"). |

The numerator of the test statistic is calculated as `(x - y) - mu`

.

Returns a list containing the following items:

`mu0 ` |
The null hypothesised difference. |

`statistic ` |
The test statistic. |

`alternative ` |
Alternative hypothesis. |

`p.value ` |
The p-value for the test. |
