Default t test in R is Welch's test, not Student's, and can be very problematic
...ow p values in real world scenarios.
If you agree with me, you might want to consider generally using Student's test instead, by using t.test(x, y, var.equal = TRUE).
Code to demonstrate the problem and play around with different scenarios, as described in the paper, is at: https://github.com/davenomiddlenamecurtis/TestTTest
