showHeatmaps: Heatmaps for JIVE Decompositions
In r.jive: Perform JIVE Decomposition for Multi-Source Data

Description Usage Arguments Details Author(s) References See Also Examples

This function draws heatmaps for the components of a JIVE decomposition.

1	showHeatmaps(result, order_by = 0, show_all = TRUE)

`result`	An object of class "jive".
`order_by`	Specifies how to order the rows and columns of the heatmap. If order_by=-1, the matrices are not re-ordered. If order_by=0, orderings are determined by joint structure. Otherwise, order_by gives the number of the individual structure dataset to determine the ordering. In all cases orderings are determined by complete-linkage hiearchichal clustering of Euclidean distances.
`show_all`	Specifies whether to show the full decomposition of the data, JIVE estimates, and noise. If show_all=FALSE, only the matrix (or matrices) that determined the column ordering is shown.

The columns correspond to the shared dimension (for example, a common sample set), and the ordering of the columns is the same for all matrices shown.
