  weighting_linear = FALSE,
  segment_ids = integer()
)

Arguments

block

Numeric matrix of connection counts

lookback_size

Examples

block <- matrix(c(1, 0,
                  2, 1,
                  3, 0,
                  4, 2), nrow = 4, byrow = TRUE)
door_lookback_block(block, lookback_size = 2L)                        # sums
#>      [,1] [,2]
#> [1,]    1    0
#> [2,]    3    1
#> [3,]    5    1
#> [4,]    7    2
