SUBSET
Description
Extracts a subset of elements from a given Vector.
SUBSET(Vector<Any>, Scalar<Number>)
Extract the first or last x entries.
SUBSET(vector: Vector<Any>, x: Scalar<Number>): Vector<Any>Parameters
vector
A vector of type any.
x
A positive or negative number. When x is a positive number it starts to extract the number of entries stated in param2 from the beginning, when param2 is a negative number it starts to extract the number of entries stated in param2 from the end of the vector.
Returns
Returns a Vector of type any.
SUBSET(Vector<any>, Scalar<Number>, Scalar<Number>)
SUBSET(vector: Vector<Any>, x: Scalar<Number>, y: Scalar<Number>): Vector<Any>Parameters
vector
A vector of type any.
x
Position from which to start extracting elements. If negative, then position is counted from the end of the vector.
y
Position until which to extract elements. If negative, then position is counted from the end of the vector.
SUBSET(Vector<Event>, Scalar<Time>)
SUBSET(vector: Vector<Event>, start: Scalar<Time>): Vector<Event>Extract entries from time start until the latest event (left argument is excluding, right is including)
Parameters
vector
A vector of type Event.
start
The start time from which to start extracting entries until the latest.
Returns
A Vector of type Event.
SUBSET(Vector<Event>, Scalar<Time>, Scalar<Time>)
SUBSET(vector: Vector<Event>, start: Scalar<Time>, end: Scalar<Time>): Vector<Event>Extract entries from time start until time end (left argument is excluding, right is including the time border)
Parameters
vector
A vector of type Event
start
The start time from which to start extracting entries. (Excluded)
end
The end time until which to extract entries. (Included)
Returns
A Vector of type Event.
Examples
Extract the last entry from the vector GridPowerConsumption.
SUBSET($GridPowerConsumption, -1)Extract all events from zero hour (midnight) until now.
SUBSET($GridPowerConsumption, lastZeroHour)Extract all events 2 days ago until 1 day ago.
SUBSET($GridPowerConsumption, now-2d, now-1d)Last updated
