Description
An "elbow plot" hopefully shows you how many clusters are appropriate, as indicated by a minimal reduction in within-group sum of squares upon increasing k. In reality, few data sets will show such an elbow, but it is nonetheless a common method.
Removes incomplete records.
Usage
1
PlotElbowKmeans(df, max.clusters = 15, plot.title = "")
Arguments
df
dataframe ready for kmeans (e.g. scaled)
max.clusters
how to deal with missing values, see stats::cor
plot.title
string to add to plot
Value
ggplot object
