Introduction to use of prcr for carrying a out two-step cluster analysis
In prcr: Person-Centered Analysis

Example

In this example using the built-in to prcr dataset pisaUSA15. Specifically, we use composite variables for broad interest, enjoyment, instrumental motivation, and self-efficacy. More information on these and other items can be found at this link.

devtools::load_all(".")

library(prcr)

df <- pisaUSA15
m3 <- create_profiles_cluster(df, broad_interest, enjoyment, instrumental_mot, self_efficacy, n_profiles = 3)
plot_profiles(m3, to_center = TRUE)

Other functions include those for carrying out comparing r-squared values and perfomring cross-validation. These are documented in the CRAN release and their versions in the in-development version will be documented prior to the CRAN release.
