Arguments

x

for rlebdm(), an rle() object or a vector that is converted to one; it will be coerced to logical() before processing; for as.rlebdm.matrix(), a matrix.

n

the dimensions of the square matrix represented.

...

additional arguments, currently unused.

compact

whether to print the matrix compactly (dots and stars) or to print it as a logical matrix.

e1, e2

arguments to the unary (e1) or the binary (e1 and e2) operators.

prototype

an optional network with network attributes that are transferred to the edgelist and will filter it (e.g., if the prototype network is given and does not allow self-loops, the edgelist will not have self-loops either,e ven if the dyad matrix has non-FALSE diagonal).

Methods (by generic)

Note

The arithmetic operators are mathematical functions are implemented for the Ops and the Math group generics and therefore work for almost all of them automatically. To preserve the integrity of the data structure, the results are cast to logical before return.
