[character]: define the aglomerative method used to compute the mean. Three methods are curently available: "all", "sample" and "hierarchical". See meanFrechet and [1] for details.

[logical]: if the agglomerationMethod is "all" or "sample", this variable is use to decide if the trajectories will be agglomerate in a random order (shuffle=TRUE) or not. If not, the lexical order based on the individual identifiant is used.

[integer]: Define the number of trajectories that will be use to compute the meanFrechet when the aggregationMethod is "sample".

[character]: define the distance between two clusters used by the hierarchical clustering when the aggregationMethod is "hierarchical". The methods available are the one for hclust

[numeric]: the maximum number of iteration allowed.
