  ## S4 method for signature 'list'
moveStack(x, forceTz=NULL, ...)
  
  ## S4 method for signature 'Move'
moveStack(x, ..., forceTz=NULL)
  
  ## S4 method for signature 'MoveStack'
moveStack(x, ..., forceTz=NULL)

Arguments

x

a list of move or moveStack objects (or a combination of both). Timestamps of all objects have to be in the same time zone.

forceTz

The time zone, as a character, that the resulting moveStack object should have (see OlsonNames() for available time zones). If NULL the timestamps of the resulting moveStack will be in the time zone of the computer (see Sys.timezone())

...

Additional move or moveStack objects.

Details

This function stacks single Move or Movestacks objects to a MoveStack object.

Value

a 'MoveStack' object

Note

All animal names are converted into 'good names' which means, that spaces are replaced with points and duplicated names get an individual number added. For example:
'Leroy, Leroy' -> adding number to duplicated names ->'Leroy, Leroy.1'
'Ricky T' -> replacing spaces -> 'Ricky.T'
