This function is used by the 'oneway' function for oneway analysis of variance in case a user requests post-hoc tests using the Tukey or Games-Howell methods.

```
posthocTGH(y, x, method=c("games-howell", "tukey"),
conf.level = 0.95, digits=2, p.adjust="none",
formatPvalue = TRUE)
```

y

y has to be a numeric vector.

x

x has to be vector that either is a factor or can be converted into one.

method

Which post-hoc tests to conduct. Valid values are "tukey" and "games-howell".

conf.level

Confidence level of the confidence intervals.

digits

The number of digits to show in the output.

p.adjust

Any valid `p.adjust`

method.

formatPvalue

Whether to format the p values according to APA standards (i.e. replace all values lower than .001 with '<.001'). This only applies to the printing of the object, not to the way the p values are stored in the object.

A list of three elements:

List with input arguments

List of intermediate objects.

List with two objects 'tukey' and 'games.howell', containing the outcomes for the respective post-hoc tests.
