David Geary's rubberband classes have been added to make the data exclusion process smoother. Also, many of the classes have been reorganized into packages.
Researchers sometimes encounter data sets that consist of many curves.
The data points in each cell are modulus of elasticity values obtained from stress-strain curves. A researcher is interested in the effect of several chemical inhibitors on the growth of several fungus species. A researcher is interested in the effects of linerboard source, corrugating medium, and adhesive type on the creep behavior of corrugated fiberboard under cyclic humidity conditions. The data points in each cell are steady-state creep rates obtained from strain versus time curves. Sometimes this process is straightforward and it can be automated.
