An R package accompanying the paperProjection pursuit based on Gaussian mixtures and evolutionary algorithms by Luca Scrucca and Alessio Serafini (2018).

You can install the released version ofppgmmga from CRAN:

install.packages("ppgmmga")

or the development version from GitHub:

# install.packages("devtools")devtools::install_github("luca-scr/ppgmmga", build = TRUE, build_opts = c("--no-resave-data", "--no-manual"))
