simu.RDPG | R Documentation |
Simulate a dot product graph (without change point). The generated data is a matrix with each column corresponding to the vectorized adjacency (sub)matrix at a time point. For example, if the network matrix is required to be symmetric and without self-loop, only the strictly lower diagonal entries are considered.

with the following structure:
obs_mat |
A matrix, with each column be the vectorized adjacency (sub)matrix. For example, if "symm = TRUE" and "self = FALSE", only the strictly lower triangular matrix is considered. |
graphon_mat |
Underlying graphon matrix. |
