Examples

## 1d
v <- Lagged(2^(0:6))
v
maxLag(v)
v[c(2,4,6)]
v[8] # NA
## reduce the number of lags in place
maxLag(v) <- 4
v
## extend the object (with NA's)
maxLag(v) <- 6
v
## extend using "["
v[5:8] <- 2^(5:8)
v

## 2d
m <- Lagged(matrix(1:12, nrow = 4))
m
maxLag(m)
maxLag(m) <- 1
m
## maxLag(m) <- 4 # extending this way doesn't work currently
