Make a binary matrix out of a weighted matrix
to_binary_matrix(mat, min)
Arguments
- mat
a numeric matrix
- min
a threshold. All values in mat of at least this minimum value
will become 1, all values smaller than this minimum will become 0.
Value
the dichotomized matrix
Details
If a cell has value smaller than a minimum value,
the cell becomes 0. If the cell has a value of at least
the minimum value, it becomes 1.
The procedure will work for any matrix, not necessarily a square one.
Examples
M <- matrix(round(runif(20),1), ncol = 4)
to_binary_matrix(M, min = .45)
#> [,1] [,2] [,3] [,4]
#> [1,] 0 0 1 0
#> [2,] 1 1 1 1
#> [3,] 0 0 0 0
#> [4,] 0 1 0 0
#> [5,] 0 1 1 1
