1 2 3 4 5 6 7 8 9 10 11 | # ways to succeed:
is_freq(2) # => TRUE, but does NOT return the frequency 2.
is_freq(1:3) # => TRUE (for vector)
# ways to fail:
is_freq(-1) # => FALSE + warning (negative values)
is_freq(1:-1) # => FALSE (for vector) + warning (negative values)
is_freq(c(1, 1.5, 2)) # => FALSE (for vector) + warning (non-integer values)
## Note that:
is.integer(2) # => FALSE!
