Bootstrapping of the effectiveness of temperature regulation (E) from the
original distributions of Te and Tb as described by Hertz et al. (1993).
One can choose the number of resamples and has the option to calculate E as
defined by Hertz et al. (1993) or Blouin-Demers & Weatherhead (2001). See
`calculate_E_hertz`

and `calculate_E_blouin`

for
more information about these two indices.
The thermal quality of the habitat (de) and accuracy of temperature
regulation (db) are calculated as part of this formula, so it is not
necessary to run `calculate_de`

and `calculate_db`

before running this function.

`te` |
A vector containing operative temperatures. |

`tb` |
A vector containing body temperature measurements. |

`tset_low` |
Lower boundary of a species or population set-point range that was determined through thermal preference trials in a temperature gradient. This may be a named double vector containing the lower boundary value, or simply the value itself. |

`tset_up` |
Upper boundary of the set-point range. |

`index` |
Either 'hertz' or 'blouin'. |

`n` |
The desired number of samples drawn with replacement. |

The mean E and its 95 percent confidence interval obtained through resampling with replacement n times.
