personas_hclust: Create hierarchical clusters of selected metrics using a Person query

Description

Apply hierarchical clustering to selected metrics. Person averages are computed prior to clustering. The hierarchical clustering uses cosine distance and the ward.D method of agglomeration.

Usage

personas_hclust(data, metrics, k = 4, return = "plot")

Value

A different output is returned depending on the value passed to the return

argument:

• "plot": 'ggplot' object. A heatmap plot comparing the key metric averages of the clusters as per keymetrics_scan().

• "data": data frame. Raw data with clusters appended

• "table": data frame. Summary table for identified clusters

• "hclust": 'hclust' object. hierarchical model generated by the function.

Arguments

data

A data frame containing PersonId and selected metrics for clustering.

metrics

Character vector containing names of metrics to use for clustering. See examples section.

k

Numeric vector to specify the k number of clusters to cut by.

return

String specifying what to return. This must be one of the following strings:

• "plot"

• "data"

• "table"

• "hclust"

See Value for more information.
