Examples

cat("\nBeispieldaten\n")
d.data <- data.frame(a = 1:20,
                     b = rep(1:10, 2),
                     c = letters[1:20],
                     d = rep(letters[1:10], 2))

cat("\nBetrachtung eines Attributes\n")
var <- c("a")
testGranularity(d.data = d.data, var = var)
testGranularity(d.data = d.data, var = var, verbose = FALSE)

cat("\nBetrachtung eines Attributes\n")
var <- c("b")
testGranularity(d.data = d.data, var = var)

cat("\nBetrachtung von zwei Attributen\n")
var <- c("a", "b")
testGranularity(d.data = d.data, var = var)

cat("\nBetrachtung von drei Attributen\n")
var <- c("a", "b", "c", "d")
testGranularity(d.data = d.data, var = var)

cat("\nBetrachtung mit einem Wert NA\n")
d.data[16, 3] <- NA
var <- c("a", "b", "c", "d")
testGranularity(d.data = d.data, var = var)

cat("\nBeispiel ChickWeight mit einem Attribut\n")
var <- c("Chick")
testGranularity(d.data = ChickWeight, var = var)

cat("\nBeispiel ChickWeight mit zwei Attributen\n")
var <- c("Chick", "Diet")
testGranularity(d.data = ChickWeight, var = var)

cat("\nBeispiel ChickWeight mit drei Attributen\n")
var <- c("Chick", "Diet", "Time")
testGranularity(d.data = ChickWeight, var = var)
