K-Means Mapping Function

Create a tibble that maps the hai_kmeans_obj() using purrr::map() to create a nested data.frame/tibble that holds n centers. This tibble will be used to help create a scree plot.

Usage

hai_kmeans_mapped_tbl(.data, .centers = 15)

kmeans_mapped_tbl(.data, .centers = 15)

Arguments

.data

You must have a tibble in the working environment from the hai_kmeans_user_item_tbl()

.centers

How many different centers do you want to try

Value

A nested tibble

Details

Takes in a single parameter of .centers. This is used to create the tibble and map the hai_kmeans_obj() function down the list creating a nested tibble.
