Converting Data between Directed Network Models and Symmetric Network Models.

homophili.data converts the matrix of explanatory variables between directed network models and symmetric network models.

homophili.data(data, nvec, to = c("lower", "upper", "symmetric"))

`data`	A `matrix` or `data.frame` of the explanatory variables of the network formation model. This corresponds to the `X` matrix in `homophily.fe` or `homophily.re`.
`nvec`	A vector of the number of individuals in the networks.
`to`	Indicates the direction of the conversion. For a matrix of explanatory variables `X` (`n(n-1)` rows), one can select lower triangular entries (`to = "lower"`) or upper triangular entries (`to = "upper"`). For a triangular `X` (`n(n-1)/2` rows), one can convert to a full matrix of `n*(n-1)` rows by using symmetry (`to = "symmetric"`).
