sample(x, size, replace = FALSE, prob = NULL)

Dari Monty Hall:

sample(doors,1)

three_values <- c(1,2,3)
sample(three_values)

3 1 2

two_values <- c(1,2)

all_values <- c(two_values, sample(two_values,1))
all_values

1 2 2

sample(all_values)

2 2 1

set1 <- c(4,3,5)
set2 <- c(4,3,9)

set1 == set2

TRUE  TRUE FALSE

Dua set tidak identik; mengembalikan FALSE:

identical(set1, set2)

FALSE

Dua set identik; mengembalikan TRUE:

set3 <- c(4,3,5)
identical(set1, set3)

TRUE
