What are the differences between t.test() and t.data.frame()? When do you use these two
Due to the naming scheme of S3’s generic class, both functions are similar to one another.
However, they are not related to each other.
t.test() performs t-test and is generic in nature.
t.data.frame() is called by the generic t() for transposing the input data.
As a result of S3 dispatch rules, t.test() along with t() would get called when the latter is
applied to the class “test”
