This function takes random walks as defined
by rw(), produces the required additional variables
(denoted using a "c" prefix and constructed using
enw_add_cumulative_membership()), and then returns the
extended data.frame along with the new fixed effects and the
random effect structure.
Value
A list containing the following:
data: The inputdata.framewith the addition of the new variables required by the specified random walk. These are added usingenw_add_cumulative_membership(). -terms: A character vector of new fixed effects terms to add to a model formula.effects: Adata.framedescribing the random effect structure of the new effects.
