TraMineR stands for Trajectory Miner in R. It is used to explore, render, and analyze the categorical sequence data. Its primary aim is to discover insights from event or states sequences describing life courses mainly from longitudinal data. Longitudinal data refers to data that is recorded repeatedly over time. A more formal definition is A dataset is longitudinal if it tracks the same type of information on the same subjects at multiple points in time (http://www.caldercenter.org/whatis.cfm). Alphabet is the list of the states allowed in the sequence.
