find.m {blockmodeling} | R Documentation |
The functions compute the maxsimum value of m/cut
where a ceratin block is still classified as alt.blocks
and not "null".
The difference between find.m
and find.m2
it that find.m
uses an optimizational approach and is faster and more precise than find.m2
. However, find.m
only supports regular ("reg") and complete ("com") as alt.blocks
, while find.m2
supports all block types. Also, find.m
does not always work, sepecially if cormat
is not "none".
find.m(M, clu, alt.blocks = "reg", diag = !is.list(clu), cormet = "none", FUN = "max") find.m2(M, clu, alt.blocks = "reg", neval = 100, ...) find.cut(M, clu, alt.blocks = "reg", cuts = "all", ...)
A matrix of maximal m/cut
values.
