### Arguments

`x, object` | a ClusterExperiment object.
`value` | The value to be substituted in the corresponding slot. See the slot descriptions in `ClusterExperiment` for details on what objects may be passed to these functions.
`ignoreUnassigned` | logical. If true, ignore the clusters with -1 or -2 assignments in calculating the number of clusters per clustering.
`whichClusters` | argument that can be either numeric or character vector indicating the clusterings to be used. See details of `getClusterIndex`.
`...` | For `addToColData`, arguments passed to `colDataClusters`.
`useNames` | for `tableClusters`, whether the output should be tabled with names (`useNames=TRUE`) or ids (`useNames=FALSE`)
`makeFactor` | logical for `colDataClusters`. If TRUE the clustering will be added to the `colData` slot as a factor. If FALSE, the clustering will be added to the `colData` slot as a character vector if `useNames=TRUE` and as a numeric vector if `useNames=FALSE`.

### Details

Note that redefining the transformation function via `transformation(x)<-` will check the validity of the transformation on the data assay. If the assay is large, this may be time consuming. Consider using a call to ClusterExperiment, which has the option as to whether to check the validity of the transformation.

### Value

`transformation` prints the function used to transform the data prior to clustering.

`nClusterings` returns the number of clusterings (i.e., ncol of clusterMatrix).

`nClusters` returns the number of clusters per clustering

`nFeatures` returns the number of features (same as 'nrow').

`nSamples` returns the number of samples (same as 'ncol').

`clusterMatrixNamed` returns a matrix with cluster labels.

`clusterMatrixColors` returns the matrix with all the clusterings, using the internally stored colors for each cluster

`clusterMatrix` returns the matrix with all the clusterings.

`primaryCluster` returns the primary clustering (as numeric).

`primaryClusterIndex` returns/sets the primary clustering index (i.e., which column of clusterMatrix corresponds to the primary clustering).

`primaryClusterIndex` returns/sets the primary clustering index (i.e., which column of clusterMatrix corresponds to the primary clustering).

`primaryClusterNamed` returns the primary cluster (using cluster labels).

`primaryClusterIndex` returns/sets the primary clustering index (i.e., which column of clusterMatrix corresponds to the primary clustering).

`dendroClusterIndex` returns/sets the clustering index of the clusters used to create dendrogram (i.e., which column of clusterMatrix corresponds to the clustering).

`coClustering` returns/sets the co-clustering matrix.

`clusterTypes` returns/sets the clusterTypes slot.

`clusteringInfo` returns the clusterInfo slot.

`clusterLabels` returns/sets the column names of the clusterMatrix slot.

`clusterLegend` returns/sets the clusterLegend slot.

`orderSamples` returns/sets the orderSamples slot.

`addToColData` returns a `ClusterExperiment` object with the clusterings in clusterMatrix slot added to the `colData` slot

`colDataClusters` returns a `DataFrame` object that has the clusterings in clusterMatrix slot added to the `DataFrame` in the `colData` slot
