SLD function

This function creates simplex lattice mixture designs

This function creates simplex lattice designs in unconstrained mixture experiment space.

SLD(fac, lev)

Arguments

• fac: This is the number of factors, this must be between 2 and 12
• lev: This is the number of levels, this must be between 2, and 5.

Returns

• SL: This is a data frame containing the simplex lattice design. The columns are labeled x1, x2 ...xn, where n is the number of mixture variables.
