The goal of traj is to form clusters of longitudinal trajectories sharing certain distinctive characteristics. The procedure involves computing a set of numerical “measures”, each capturing a certain feature of the trajectory, and using a Spectral Clustering algorithm on those to identify the clusters.
You can install the development version of traj from GitHub with:
# install.packages("devtools")
devtools::install_github("IcatianTrout/traj")See the vignette.
