chlorph {durham} | R Documentation |
The data come from a semiautomated process for measuring the actual amount of chlorpheniramine maleate in tablets nominally containing 4mg. The tablets used for the study were made by two different manufacturers. For each manufacturer, a composite was produced by grinding together a number of tablets. Each composite was split into seven pieces each of the same weight as a tablet and the pieces were sent to seven different laboratories. Each laboratory made 10 separate measurements on each composite.
