Description Usage Arguments Value Examples
Combine the posterior probabilities for combinations of individual traits/studies according to the association patterns from which those traits/studies all come from the alternative distribution. Provides the posterior probability of being associated with "at least traits X, Y and Z", for example. Can also require non-null association with one or more traits/studies and combine over patterns where that/those trait(s) also come from the alternative distribution.

|
post_prob |
matrix of posterior probabilities. |
combos |
matrix or integer specifying combinations. When matrix, each row is
a combination, with column indices of traits belonging to the combination specified in
columns of |
req_idx |
(optional) scalar or integer vector of trait(s) where a non-null
association is required (i.e. from the alternative distribution).
If |
prefix |
character string denoting prefix of column names for the results matrix. |
A numeric matrix of combined posterior probabilities.
