tidy.pairwise.htest {broom} | R Documentation |
Tidy a pairwise.htest object, containing (adjusted) p-values for multiple pairwise hypothesis tests.
## S3 method for class 'pairwise.htest' tidy(x, ...)
x |
a "pairwise.htest" object |
... |
extra arguments (not used) |
Note that in one-sided tests, the alternative hypothesis of each test can be stated as "group1 is greater/less than group2".
Note also that the columns of group1 and group2 will always be a factor, even if the original input is (e.g.) numeric.
A data frame with one row per group/group comparison, with columns
group1 |
First group being compared |
group2 |
Second group being compared |
p.value |
(Adjusted) p-value of comparison |
