characterTrajectories: Character Trajectories Data Set

Description

Subset of the 'Character Trajectories Data Set' from the UCI Machine Learning Repository. The data set consists of trajectories of the tip of a pen whilst writing the letter 'a'. All samples are from the same writer. Original data has been processed.

Usage

data(characterTrajectories)

Format

Three dimensional array. The first dimension represents time. The second dimension corresponds to the observation number. The third dimensions contains the X and Y coordinates.
