A set of generators for character vectors.

Usage

character_(len = c(1L, 10L), any_na = FALSE, any_empty = FALSE)

character_letters(len = c(1L, 10L), any_na = FALSE, any_empty = FALSE)

character_numbers(len = c(1L, 10L), any_na = FALSE, any_empty = FALSE)

character_alphanumeric(len = c(1L, 10L), any_na = FALSE, any_empty = FALSE)

Arguments

len

Length of the generated vectors. If len is a single number all vectors will have this length. If len is a numeric vector of length 2 it will produce vectors with lengths between a minimum and maximum, inclusive. For example len = c(1L, 10L) would produce vectors with lengths between 1 and 10. To produce empty vectors set len = 0L or a range like len = c(0L, 10L).

any_na

Whether NA values should be allowed.

any_empty

Whether empty character values should be allowed.

Value

A quickcheck_generator object.

Examples

character_() %>% show_example()
#> [1] "8]^E*x" "whP"    "x"      "bv"     "h`~"    "O"      "Z4$:"  
character_(len = 10L, any_na = TRUE) %>% show_example()
#>  [1] "hQ"       "0&.<"     "{^"       "|V\\qgO`" "'!sUh4-"  NA        
#>  [7] NA         "uGx2~"    NA         NA        
character_(len = 10L, any_empty = TRUE) %>% show_example()
#>  [1] ""         ""         "+"        "[(??n"    "-qhP78"   ""        
#>  [7] "~Feh"     "!#Jw:d~K" ""         "zC"
