Methods to serialize objects into numeric vectors for passing to the C side.
These methods return a vector of doubles. For edge lists, this
usually takes the form of a 2 e + 1- or 3 e + 1-vector,
containing the number of edges followed a column-major
serialization of the edgelist matrix.
## S3 method for class 'network' to_ergm_Cdouble(x, attrname = NULL, ...) ## S3 method for class 'matrix' to_ergm_Cdouble(x, prototype = NULL, ...) ## S3 method for class 'rlebdm' to_ergm_Cdouble(x, ...) to_ergm_Cdouble(x, ...)
x |
object to be serialized. |
attrname |
name of an edge attribute. |
... |
arguments for methods. |
prototype |
A network whose relevant attributes (size,
directedness, bipartitedness, and presence of loops) are imposed
on the output edgelist if |
The rlebdm method returns a vector with the following:
number of nonzero dyads,
number of runs of nonzeros,
starting positions of the runs, and
cumulative lengths of the runs, prepended with 0.
