hai_umap_list: UMAP Projection

Description

Create a umap object from the uwot::umap() function.

Usage

hai_umap_list(.data, .kmeans_map_tbl, .k_cluster = 5)
umap_list(.data, .kmeans_map_tbl, .k_cluster = 5)

Value

A list of tibbles and the umap object

Arguments

.data

The data from the hai_kmeans_user_item_tbl() function.

.kmeans_map_tbl

The data from the hai_kmeans_mapped_tbl().

.k_cluster

Pick the desired amount of clusters from your analysis of the scree plot.
