toa_diff: Difference in Time of Adoption (TOA) between individuals
Description
Creates \(n \times n\) matrix indicating the difference in times of adoption between
each pair of nodes
Usage
toa_diff(obj, t0 = NULL, labels = NULL)
Value
An \(n \times n\) symmetric matrix indicating the difference in times of
adoption between each pair of nodes.
Arguments
obj
Either an integer vector of size \(n\) containing time of adoption of the innovation,
or a diffnet object.
t0
Integer scalar. Sets the lower bound of the time window (e.g. 1955).
labels
Character vector of size \(n\). Labels (ids) of the vertices.

Details
Each cell ij of the resulting matrix is calculated as \(toa_j - toa_i\), so that whenever its positive it means that the j-th individual (alter)
adopted the innovation sooner.
