nextState
Syntax
nextState(X)
Arguments
X is a vector or matrix of temporal/Boolean/numeric type.
Details
Consecutive elements in X with the same value feature the same state, and a NULL value has no state. The state of each element is equal to its value. Return the next state of the current state for each element in X. If it is NULL, return the next adjacent state.
If X is a matrix, return the next state for each column of the matrix.
Examples
X = [1, 2.2, NULL, 2.2, 2.3, 1, 1.2]
next(X)
// output
[2.2,,2.2,2.3,1,1.2,]
nextState(X)
// output
[2.2,2.2,2.2,2.3,1,1.2,]
X = matrix([1.0, 1.1, 1.0, 0.9], [NULL, 1.3, 2.5, 5.5], [5.5, 4.2, 1.6, 1.8])
nextState(X)| #0 | #1 | #2 |
|---|---|---|
| 1.1 | 1.3 | 4.2 |
| 1 | 2.5 | 1.6 |
| 0.9 | 5.5 | 1.8 |
