Permeability of building materials
Description
The permeability of building materials
Usage
data(perm)
Format
A data frame with 81 observations on the following 3 variables.
Daythe day;
a factor with levels 1 up to 9
Machthe machine used for measurement;
a factor with levels A, B or C
Permthe permeability in seconds:
a numeric vector
Details
The data give the average permeability (in seconds)
of eight sheets of building materials,
using random samples of 81 sheets in three machines over nine days,
with three measurements for each machine–day combination.
