MoveStack-class: The MoveStack class

Description

The MoveStack object is a stack of move objects. A MoveStack object can be created with the functions move, moveStack, getMovebankData or getDataRepositoryData

Arguments

Slots

bbox: belongs to the SpatialPointsDataFrame
citation: Object of class "character": how to cite the study, when Movebank data are used
coords: coordinates of the track, belongs to the SpatialPointsDataFrame
coords.nrs: belongs to the SpatialPointsDataFrame
data: Object of class "data.frame": additional data associated to the coordinates
dataUnUsedRecords: Object of class "data.frame": data associated to the unused records
dateCreation: Object of class "POSIXct": timestamp when the MoveStack object was created
idData: Object of class "data.frame": additional (one row) data. These data contain information associated to the animal
license: Object of class "character": the license under which the data were published, when Movebank data are used
proj4string: Object of class "CRS": projection of the coordinates
sensor: Object of class "factor": sensors used to record the coordinates
sensorUnUsedRecords: Object of class "factor": sensors used to record the unused records
study: Object of class "character": name of the study, when Movebank data are used
timestamps: Object of class "POSIXct": timestamps associated to the coordinates
timestampsUnUsedRecords: Object of class "POSIXct": timestamps associated to the unused records, i.e. lines of the data that were removed because they included NA locations
trackId: Object of class "factor": vector that indicates, which data, coordinates and timestamps belong to each individual
trackIdUnUsedRecords: Object of class "factor": vector that indicates, which data, coordinates and timestamps of the unused records belong to each individual
