profile_plot: Cluster profile plots

In Rkabacoff/qacr: Functions to Facilitate Data Science Projects

Description

profile_plot generates a mean profile plot for each cluster in a cluster analysis.

Usage

profile_plot(data, cluster = "cluster", type = c("bar", "line"))

Arguments

data	a data frame.
cluster	variable containing cluster membership.
type	character. "bar" or "line" plots.

The data frame must contain numeric variables for all variables except the cluster variable. The cluster variable can be numeric, character, or factor. The data will be standardized before plotting. The bar charts are faceted, while the line charts are grouped.

Value

a ggplot2 graph

Examples

# 3 cluster solution
iris <- qacr::standardize(iris)
df <- iris[-5]
set.seed(1234)
fit <- kmeans(df, 3)
df$cluster <- fit$cluster
profile_plot(df, type="bar")
profile_plot(df, type="line")
