Examples

# Generate random linkage input
x <- data.frame(
    a = sample(letters[seq(3)], 10, replace = TRUE),
    A = sample(LETTERS[seq(3)], 10, replace = TRUE)
)

# Create LinkMap
LinkMap(x)
#>    a A
#> 1  c C
#> 2  a C
#> 3  b A
#> 4  c B
#> 5  c B
#> 6  c C
#> 7  b C
#> 8  a B
#> 9  a C
#> 10 a A
