Usage

is_valid_ish(
  x,
  min_len = 1,
  max_len = Inf,
  mode = NA,
  na = TRUE,
  blank = FALSE,
  all = FALSE
)

Arguments

x

data to check

min_len, max_len

minimal and maximum length

mode

which storage mode (see mode) should x be considered valid. Default is NA: disabled.

na

whether NA values considered invalid?

blank

whether blank string considered invalid?

all

if na or blank is true, whether all element of x being invalid will result in failure?

Value

logicals whether input x is valid

Examples


# length checks
is_valid_ish(NULL)                     # FALSE
#> [1] FALSE
is_valid_ish(integer(0))               # FALSE
#> [1] FALSE
is_valid_ish(integer(0), min_len = 0)  # TRUE
#> [1] TRUE
is_valid_ish(1:10, max_len = 9)        # FALSE
#> [1] FALSE

# mode check
is_valid_ish(1:10)                     # TRUE
#> [1] TRUE
is_valid_ish(1:10, mode = 'numeric')   # TRUE
#> [1] TRUE
is_valid_ish(1:10, mode = 'character') # FALSE
#> [1] FALSE

# NA or blank checks
is_valid_ish(NA)                     # FALSE
#> [1] FALSE
is_valid_ish(c(1,2,NA), all = FALSE) # FALSE
#> [1] FALSE
is_valid_ish(c(1,2,NA), all = TRUE)  # TRUE as not all elements are NA
#> [1] TRUE

is_valid_ish(c('1',''), all = FALSE)  # TRUE
#> [1] TRUE
is_valid_ish(1:3, all = FALSE)        # TRUE as 1:3 are not characters
#> [1] TRUE
