Retrieves a time series o state vectors received from a specified aircraft during a given time interval. A state vector is a collection of data elements that characterize the status of an aircraft at a given point during a flight (such as latitude, longitude, altitude, etc.)

The time point must be specified as a date-time string in any format that can be unambiguously converted to POSIXct (such as YYYY-MM-DD HH:MM:SS). Time resolution for the time series of state vectors must be specified in seconds. Time resolution is limited to 10 s for anonymous users, and 5 s for registered users.

getAircraftStateVectorsSeries(aircraft, startTime, endTime, 
                              timeZone=Sys.timezone(), timeResolution, 
                              username=NULL, password=NULL,
                              useImpalaShell=FALSE, timeOut=60, maxQueryAttempts=1)

`aircraft`	string with the ICAO 24-bit address of an aircraft (for example, \"346190\" for Air Nostrum EC-NCD (ATR 72-600), or a character vector with multiple ICAO 24-bit addresses. In the default behavior, data is retrieved for any aircraft.
`startTime`	date-time string indicating the starting time of the interval for which state vectors should be retrieved. Must be in a format that can be unambiguously converted into POSIXct time. Valid examples are \"2011-03-27 01:30:00\" and \"2011/03/27 01:30:00\".
`endTime`	date-time string indicating the ending time of the interval for which state vectors should be retrieved. Must be in a format that can be unambiguously converted into POSIXct time. Valid examples are \"2011-03-28 01:30:00\" and \"2011/03/28 01:30:00\".
`timeZone`	string with the name of the time zone for time. For details on supported time zones, see help(timezones). By default, the system time zone is used.
`timeResolution`	time resolution in seconds to be used for the requested timeseries of state vectors. Limited to 5 s for anonymous users and 10 s for registered users.
`username`	optional string with the username to use for authentication for the OpenSky API. By default, no authentication is performed.
`password`	optional string with the password to use for authentication for the OpenSky API. By default, no authentication is performed.
`useImpalaShell`	logical indicating whether or not to use the OpenSky impala shell instead of the API to retrieve state vectors. If used, the provided username and password are used for the ssh connection. By default, the impala shell is not used.
`timeOut`	number of seconds after which the query will time out and return a NULL result. In the default behavior, timeout will be reached after 60 seconds.
`maxQueryAttempts`	On rare occassions, queries to the OpenSky Network live API can return malformed responses. This is the maximum number of attempts to obtain a properly formatted response when carrying out the requested query. It should be noted that the query will still terminate if a timeout is reached. In the default behavior, a single attempt will be performed. It is not recommended to change this to a very large number, since it can lead to long running times.

An openSkiesStateVectorSet object with field time_series=TRUE. For details on the information stored in state vectors, see the documentation for openSkiesStateVector and openSkiesStateVectorSet.
