The Vdgraph package provides functions for creating Variance Dispersion Graphs and Fraction of Design Space Plots of a standardized response surface design stored in a matrix or a data frame.

The function `Vdgraph(des)`

creates the variance dispersion graph of the response surface design stored in the matrix or data frame `des`

. The function `FDSPlot(des)`

creates the fraction of design space plot of the response surface design stored in the matrix or data frame `des`

. Useful response surface designs are also included as matricies in the package. These include the hexagonal design for two factors `Hex2`

, the small composite designs for 3 to 6 factors and Roquemore's hybrid designs for 3 to 6 factors. The function Compare2Vdg makes the variance dispersion graphs of two designs on the same scale for comparison.
