Examples


### two individual vectors

var01 <- runif(n = 50, min = 1, max = 10)
var02 <- runif(n = 50, min = 1, max = 10)

cosim(var01, var02)
#> [1] 0.7942549


### data frame

data("gdsm_df")

cosim("var03", "var04", gdsm_df)
#> [1] 0.7827041


### matrix

data("gdsm_mat")

cosim("var05", "var06", gdsm_mat)
#> [1] 0.7909028
