hai_kmeans_user_item_tbl {healthyR.ai} | R Documentation |
K-Means User Item Tibble
Description
Takes in a data.frame/tibble and transforms it into an aggregated/normalized user-item tibble of proportions. The user will need to input the parameters for the rows/user and the columns/items.
Usage
hai_kmeans_user_item_tbl(.data, .row_input, .col_input, .record_input)
kmeans_user_item_tbl(.data, .row_input, .col_input, .record_input)
Arguments
.data |
The data that you want to transform |
.row_input |
The column that is going to be the row (user) |
.col_input |
The column that is going to be the column (item) |
.record_input |
The column that is going to be summed up for the aggregation and normalization process. |
Details
This function should be used before using a k-mean model. This is commonly referred to as a user-item matrix because "users" tend to be on the rows and "items" (e.g. orders) on the columns. You must supply a column that can be summed for the aggregation and normalization process to occur.
Value
A aggregated/normalized user item tibble
