compress(rlebdm)
: Compress the rle
data structure in the
rlebdm
by merging successive runs with identical values.
as.edgelist(rlebdm)
: Convert an rlebdm
object to an edgelist
: a two-column
integer matrix or tibble
giving the cells with TRUE
values.
as.rlebdm(matrix)
: Convert a square matrix of mode coercible to logical
to an
rlebdm
.
as.rlebdm(edgelist)
: Convert an object of class edgelist
to an rlebdm
object
whose cells in the edge list are set to TRUE
and whose other
cells are set to FALSE
.
as.rlebdm(network)
: Convert an object of class network
to an rlebdm
object
whose cells corresponding to extant edges are set to TRUE
and
whose other cells are set to FALSE
.
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.
