## Lasttoggle

### Description

A data structure used by `tergm` for tracking of limited information about dyad edge histories.

### Details

The `tergm` package handles durational information attached to `network` objects by way of the `time` and `lasttoggle` network attributes. The `lasttoggle` data structure is a 3-column matrix; the first two columns are tails and heads (respectively) of dyads, and the third column is the last time at which the dyad was toggled. The default last toggle time is `-INT_MAX/2`. Last toggle times for non-edges are periodically cleared in the C code. The `time` network attribute is simply an integer, and together with the `lasttoggle` data it determines the age of an extant tie as `time + 1` minus the last toggle time for that dyad. The default value for `time` is 0.
