Examples

# From a random incidence matrix I(25X4)
I <- matrix(rbinom(100, 1, .5), nrow = 25, ncol = 4,
     dimnames = list(NULL, c("A", "B", "C", "D")))
J <- sim(I, "Jaccard")
distant(J, t = TRUE)
#>           A         B         C
#> B 0.6818182                    
#> C 0.7000000 0.3684211          
#> D 0.6111111 0.5714286 0.5000000
#Same results
sim(I, "Jaccard", distance = TRUE)
#>           A         B         C
#> B 0.6818182                    
#> C 0.7000000 0.3684211          
#> D 0.6111111 0.5714286 0.5000000
