plot_cluster: Visualize clustering results

In campbio/musicatk: Mutational Signature Comprehensive Analysis Toolkit

Visualize clustering results

Description

The clustering results can be visualized on a UMAP panel. Three different types of plots can be generated using this function: cluster-by-signature plot, cluster-by-annotation plot, and a single UMAP plot.

Usage

plot_cluster(
  result,
  clusters,
  group = "signature",
  annotation = NULL,
  plotly = TRUE
)

Arguments

result	A musica_result object generated by a mutational discovery or prediction tool. A two-dimensional UMAP has to be stored in this object.
clusters	The result generated from cluster_exposure function.
group	A single character string indicating the grouping factor. Possible options are: "signature" (columns are signatures in a grid), "annotation" (columns are sample annotation), and "none" (a single UMAP plot). Default is "signature".
annotation	Column name of annotation.
plotly	If TRUE, the plot will be made interactive using plotly.

Value

Generate a ggplot or plotly object.

Examples

set.seed(123)
data(res_annot)
#Get clustering result
clust_out <- cluster_exposure(result = res_annot, nclust = 2)
#UMAP
create_umap(result = res_annot)
#generate cluster X signature plot
plot_cluster(result = res_annot, clusters = clust_out, group = "signature")
#generate cluster X annotation plot
plot_cluster(result = res_annot, clusters = clust_out, group = "annotation",
            annotation = "Tumor_Subtypes")
#generate a single UMAP plot
plot_cluster(result = res_annot, clusters = clust_out, group = "none")
