In TukeyC: Conventional Tukey Test

##
## Example: Factorial Experiment (FE)
##

## The parameters can be: formula, aov, lm or lmer.

## Note: Upper case for factors and lowercase for levels

library(TukeyC)
data(FE)

## From: formula
## Nested: k1/p2/N
## The indices (1, 2, ...) are used to set the level of the factor
