Contemporary software commonly used to design stated preference experiments are expensive and the code is closed source. spdesignR is a free software package with an easy to use interface to make flexible stated preference experimental designs using state-of-the-art methods.
Currently the block argument of the generate_design function is not implemented, but is in the code as a placeholder. When blocking, we need to make sure that the blocking variable is orthogonal to the rest of the design to avoid introducing correlation between our attributes and the blocking variable.
