Functions in mixexp (1.2.7)

Burn

Data from Table 4 in Gallant,Prickett, Cesarec, and Bruck(2008)

ModelPlot

This function makes contour plots of a user-supplied model in the simplex mixture space.

MixturePlot

This function makes contour plots in the simplex mixture space.

Fillv

This function Creates interior points in an existing mixture design.

Nrows

Loads compiled fortran in shared file cnvrt and returns the number of rows in the resulting design
