Add a single new trajectory to trajectory array.

mt_add_trajectory(data, use = "trajectories", save_as = use,
xpos = NULL, ypos = NULL, xypos = NULL, id = "new")

## Arguments

data a mousetrap data object created using one of the mt_import functions (see mt_example for details). Alternatively, a trajectory array can be provided directly (in this case use will be ignored). a character string specifying which trajectory data should be used. a character string specifying where the resulting trajectory data should be stored. a vector of x positions. Ignored, if xypos is provided. a vector of y positions. Ignored, if xypos is provided. a matrix, the first column corresponding to the x positions, the second to the y positions. a character string specifying the identifier of the to be added trajectory.

## Value

A mousetrap data object (see mt_example) where the new trajectory has been added. If the trajectory array was provided directly as data, only the trajectory array will be returned.
