Three quality characteristics (inner diameter, thickness and length) are measured in a specific carbon fiber tube. This dataset consist of 30 samples of size 8 were collected and the process is assumed to be stable.
data(carbon1)
An array of dimensions 30 x 3 x 8.
"inner diameter"
is the inner diameter of the tubes
"thickness"
is the thickness
"length"
is the length
# NOT RUN { data(carbon1) ## maybe str(carbon1) ; plot(carbon1) ... # }
