In ARTool: Aligned Rank Transform

Synthetic 2x2x2 Within-Subjects Experiment

Description

Synthetic data from an experiment with three within-subjects factors (A, B, and C) having two levels each.

Format

A data frame with 64 observations on the following 5 variables.

S

a factor representing subjects with levels "s1" .. "s8"

A

a factor with levels "a1" "a2"

B

a factor with levels "b1" "b2"

C

data(ElkinABC, package = "ARTool")

## run contrast using the ART-C procedure on the data.
m <- art(Y ~ A*B*C + (1|S), data = ElkinABC)
