comp_comp_pair is a function that takes 0, 1, or 2 probabilities (p1 and p2) as inputs. If either of them is missing (NA), it computes the complement of the other one and returns both probabilities.

comp_comp_pair(p1 = NA, p2 = NA)

## Arguments

p1 A numeric probability value (in range from 0 to 1). p1 is optional when p2 is provided. A numeric probability value (in range from 0 to 1). p2 is optional when p1 is provided.

## Value

A vector v containing 2 numeric probability values (in range from 0 to 1): v = c(p1, p2).

## Details

comp_comp_pair does nothing when both arguments are provided (i.e., !is.na(p1) & !is.na(p2)) and only issues a warning if both arguments are missing (i.e., is.na(p1) & is.na(p2)).

Inputs are not verified: Use is_prob to verify that an input is a probability and is_complement to verify that two provided values actually are complements.
