Codoc mismatches from documentation object 'exact_rank_prob', 'get_rankings'

[barracuda156]

I guess this is to be fixed:

* checking for missing documentation entries ... OK
* checking for code/documentation mismatches ... WARNING
Codoc mismatches from documentation object 'exact_rank_prob':
exact_rank_prob
  Code: function(P, only.results = TRUE, verbose = FALSE, force =
                 FALSE)
  Docs: function(P, only.results = T, verbose = F, force = F)
  Mismatches in argument default values:
    Name: 'only.results' Code: TRUE Docs: T
    Name: 'verbose' Code: FALSE Docs: F
    Name: 'force' Code: FALSE Docs: F

Codoc mismatches from documentation object 'get_rankings':
get_rankings
  Code: function(data, force = FALSE)
  Docs: function(data, force = F)
  Mismatches in argument default values:
    Name: 'force' Code: FALSE Docs: F

* checking Rd \usage sections ... OK
