plot.EFAkmeans | R Documentation |
This function creates a plot to visualize the Within-cluster Sum of Squares (WSS) for different numbers of clusters (K) in the context of exploratory factor analysis. The plot helps identify the most appropriate number of factors by showing how WSS decreases as the number of factors (or clusters) increases.

## Take the data.bfi dataset as an example.
data(data.bfi)
response <- as.matrix(data.bfi[, 1:25]) ## Load data
response <- na.omit(response) ## Remove samples with NA/missing values
## Transform the scores of reverse-scored items to normal scoring
response[, c(1, 9, 10, 11, 12, 22, 25)] <- 6 - response[, c(1, 9, 10, 11, 12, 22, 25)] + 1
EFAkmeans.obj <- EFAkmeans(response)
## Plot the EFA K-means clustering results
plot(EFAkmeans.obj)
