  na = TRUE,
  blank = FALSE,
  all = FALSE
)

mode	which storage mode (see mode) should x be considered valid. Default is NA: disabled.
na	whether NA values considered invalid?

Examples

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

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

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

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