FlexibleLagged-class {lagged}

Class FlexibleLagged

Description

Class FlexibleLagged.

Objects from the Class

Objects can be created by calls of the form new("FlexibleLagged", data, ...), see also convenience function Lagged,

"FlexibleLagged" is used mainly in programming as a superclass of classes which need to inherit from all "Lagged" classes. It can represent objects from any subclass of "Lagged". Methods are defined, such that the internal representation is transparent.

Slots

data:

Object of class "Lagged" ~~

Examples

## Lagged1d
v <- 1:12
v_lagged <- Lagged(v)
v_lagged
identical(v_lagged, new("Lagged1d", data = v)) # TRUE
v_lagged[0:2] # v[1:3]
v_lagged[[0]] # 1

## Lagged2d
m <- matrix(1:12, nrow = 4)
m_lagged <- Lagged(m)
m_lagged
identical(m_lagged, new("Lagged2d", data = m)) # TRUE
m_lagged[0] # matrix with 1  column
m_lagged[[0]] # numeric

## Lagged3d
a <- array(1:24, dim = c(2, 3, 4))
a_lagged <- Lagged(a)
identical(a_lagged, new("Lagged3d", data = a)) # TRUE

dim(a_lagged[0]) # c(2,3,1)
a_lagged[0]
a[ , , 1, drop = FALSE]

dim(a_lagged[[0]]) # c(2,3)
a_lagged[[0]]
a[ , , 1, drop = TRUE]

## as above "FlexibleLagged"
## 1d
v_flex <- new("FlexibleLagged", data = v)
identical(v_flex@data, v_lagged) # TRUE
v_flex[0]   # = v_lagged[0]
