I have been trying to run this analysis and finally want to ask for help. I am trying to run a paired t-test in which I have 19 subjects who have reaction times for 5 different conditions. The data frame has 114 rows total (6 rows for each subject representing six average reaction times by condition). Is there a way to run all paired t-tests where a paired t-test is run for every possible combination?
