Description

design() works like dplyr's function data_frame(). New columns can be defined in terms of previous columns.

Usage

design(..., .unjoin = NULL)

Arguments

...	Named arguments.
.unjoin	When a vector identifying groups, and if the variables in ... are unique within groups, the design matrix is reduced to one value per group.

Details
