Usage

as_matrix(x, ...)

# S3 method for class 'cooccurrence'
as_matrix(x, type = c("normalized", "raw"), ...)

Arguments

x

A cooccurrence data frame.

...

Ignored.

type

Character. "normalized" (default) or "raw".

Value

A numeric matrix.

Examples

res <- cooccurrence(list(c("A","B","C"), c("B","C"), c("A","C")))
as_matrix(res)
#>   A B C
#> A 0 1 2
#> B 1 0 2
#> C 2 2 0
as_matrix(res, type = "raw")
#>   A B C
#> A 0 1 2
#> B 1 0 2
#> C 2 2 0
