## Wrapper function for visualization of significant isoforms from Differentially Spliced Genes

### Description

`seeDS` This function provides visualisation tools for Significant Isoforms in a time course experiment. The function calls the `see.genes` function for selected Isoforms. This cluster will be the reference in `tableDS` function to identify the trends that follows the isoforms of a specific gene.

### Usage

     seeDS(get, rsq=0.4, cluster.all=TRUE, plot.mDSG=FALSE, k=6, cluster.method="hclust", k.mclust=FALSE)

### Arguments

`get` | a `getDS` object a cluster of flat Isoform
`cluster.all` | TRUE to make the cluster with significant isoforms of all the genome. FALSE to make the cluster with significant isoforms of Differentially Spliced Genes.
`rsq` | Required when cluster.all=TRUE. It is the cut-off level at the R-squared value for detecting significant isoforms of all the genome.
`plot.mDSG` | TRUE to make a cluster with the Isoforms belonging to monoIsoform genes
`k` | number of clusters for data partioning
`k.mclust` | TRUE for computing the optimal number of clusters with Mclust algorithm
`cluster.method` | clustering method for data partioning. Currently `"hclust"`, `"kmeans"` and `"Mclust"` are supported

### Details

The cluster reference can be made with significant isoforms of all the genome or with the isoforms belonging to the Differentially Spliced Genes.

Alternatively a cluster of monoIsoforms can be asked.

Next a partioning of the data is generated using a clustering method.

The results of the clustering are visualized in two plots as in `see.genes`.

### Value

Experiment wide Isoform profiles and by group profiles plots are generated for each data cluster in the graphical device.

`Model` | a `IsoModel` object to be used in the following steps
`get` | a `get.siggenes` object to be used in the following steps
`NumIso.by.gene` | Number of selected Isoforms for each Differentially Spliced Gene
`cut` | vector indicating gene partioning into clusters
`names.genes` | vector with the name of the gene each selected isoform belongs to
