set.seed(12)
v1 <- sample(letters[1:5], size = 5, TRUE)
ul(v1)

# return the list of position of duplicated value.
v2 <- sample(letters[1:5], size = 5, FALSE)
dup(v1)
dup(v2)

# Sort string vectors in numerical order
v3 <- sort(paste0("V", as.character(1:13)))
char_sort(v3)

# create factor with levels by numerical order
char_fct(v3)

# head and tail for strings
v4 <- sapply(1:3, function(i) paste(sample(c("A","T","G","C"), 10, TRUE), collapse = ""))
str_head(v4, 3)
