pipeline | R Documentation |
Researchers at National Institutes of Standards and Technology (NIST) collected data on ultrasonic measurements of the depths of defects in the Alaska pipeline in the field. The depth of the defects were then remeasured in the laboratory. These measurements were performed in six different batches. The laboratory measurements are more accurate than the in-field measurements, but more time consuming and expensive.
