clust |
numerical matrix whose columns contain the parameters of the clusters. |
prec |
optional positive integer. Number of decimal places for rounding. |
ncol |
number of columns describing the clusters. See details. |
dz |
optional boolean. With |
Since clusters found by oregMclust
or circMclust
often
differ only by rounding errors, the function
deldupMclust
can be used for rounding and deleting
duplicates. If clust
has a column named "count", its
values are summed appropriately. Otherwise such a column is added.
For parameter clust
the object returned from oregMclust
or circMclust
can be used. Alternatively, an arbitrary matrix
can be given, of which the first ncol
columns describe the
clusters.
The parameter prec
is the number of decimal places for
rounding; the default is no rounding.
With ncol
, the number of columns that describe the clusters
can be given. This is not needed, if clust
is an object
returned from oregMclust
or circMclust
.
An object of the same type as clust
.
