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".

M |
A matrix representing the (usually valued) network. For now, only one-relational networks are supported. The network can have one or more modes (diferent kinds of units with no ties among themselvs. If the network is not two-mode, the matrix must be square. |
clu |
A partition. Each unique value represents one cluster. If the nework is one-mode, than this should be a vector, else a list of vectors, one for each mode |
alt.blocks |
Only one of allowed blocktypes, as alternative to the null block: |
diag |
(default = |
cormet |
Which metho should be used to correct for diferent maxismum error contributins? |
FUN |
(default = "max") Function f used in row-f-regular, column-f-regular, and f-regular blocks. |
cuts |
The cuts which should be evaluatated. If |
neval |
Number of different |
half |
Should the returned value of m be one half of the value where the incosnistencies are the same. |
ms |
The values of m where the function should be evaluated. |

Other parameters to crit.fun |
A matrix of maximal m/cut
values.
