Given a vector of variables of interest for students in a single school, extracts a single value for the school

1 | ```
agg(x)
``` |

`x` |
a vector containing student-level observations for a school. If it is a factor it must contain only a single level. |

If the input is numeric, `agg`

returns the mean; if the input is not numeric, an error will be thrown unless all values are the same, in which case the single unique value will be returned.

A single value of the same type as the input vector.
